Ultimate Equations Handbook
Nomenclature-a system of naming and writing formulas for chemical compounds using the “chemical alphabet”; the symbols of elements. Exercise 1-1 and 1-2; answer these from the reading of pages You may write on the copies, but the answer sheet only will be accepted at the end of each assignment.
2
I.U.P.A.C. recommendations
Because new elements are being synthesized and disagreement exists among chemists regarding new names, a system for new element names has been proposed. Latin prefixes are used with the –ium suffix See pages 6-7 in handout. Would this system be a better way to name all elements and compounds? What would the name of table salt (NaCl) be? Ununium unseptide!

Most elements do not exist in their elemental state
Most elements do not exist in their elemental state! We have to be able to name their compounds Mercury is a natural component of the earth, with an average abundance of approximately 0.05 mg/kg in the earth’s crust, with significant local variations. Mercury ores that are mined generally contain about one percent mercury, although the strata mined in Spain typically contain up to percent mercury. While about 25 principal mercury minerals are known, virtually the only deposits that have been harvested for the extraction of mercury are cinnabar (HgS).

Inorganic Formulas and Nomenclature….handbook Ch. 2
Binary Molecules (nonmetal + nonmetal) Naming: use prefixes on page 9 to specify the number of atoms in the formula. DO NOT use the prefix mono- for the first element. Add the suffix -ide to the second element Examples; CO2 carbon dioxide N2O4 dinitrogen tetraoxide P4S10 tetraphosphorous decasulfide
5
Inorganic Formulas and Nomenclature
3. Writing formulas: write symbols with subscripts that equal the number specified by the prefixes in the name. 4. Examples: silicon dioxide SiO2 diarsenic tritelluride As2Te3 bromine monochloride BrCl
6
Nonmetal “stems” Element Stem (add –ide) oxygen ox chlorine chlor
Carbon carb iodine iod bromine brom selenium selen nitrogen nitr phosphorus phosph fluorine fluor sulfur sulf silicon silic arsenic arsen tellurium tellur astatine astat boron bor
7
Polyatomic elements Some nonmetals combine with each other to form diatomic molecules, these are the H-O-F-Br-I-N-Cl elements. O Must show that two atoms are combined 2 Natural form of sulfur is S8, phosphorus is P4
8
Molecules only practice:
1. As4O10 tetraarsenic decaoxide 2. N2O5 Dinitrogen pentaoxide 3. ICl3 Iodine trichloride 4. PCl5 Phosphorous pentachloride 5. CCl4 Carbon tetrachloride
9
Molecules only practice:
6. CCl4 Carbon tetrachloride 7. CO Carbon monoxide 8. N2O Dinitrogen monoxide 9. SiI4 Silicon tetraiodide 10. P3N5 Phosphorous pentanitride
10
Molecules only practice:
11. NI3 Nitrogen triiodide 12. P4S10 Phosphorous decasulfide 13. SiS Silicon disulfide 14. Cl2O7 Dichlorine heptoxide 15. BF3 Boron trifluoride
11
Salts vs. Molecules Metals easily lose electrons, this makes a metallic atom into an ion with a _____charge. These are called cations. Nonmetals easily gain electrons, this makes a nonmetallic atom into an ion with a _____charge. These are called anions. In a salt, the opposite charges of the cations and anions create an attractive force between the ions, an ionic bond.
12
Salts vs. Molecules The charged end of an ionic unit attracts other units and forms a large crystal. Salts exist in this form: many ionic units attracting one another in a crystal. In a molecule, the atoms of each nonmetal share electrons, so neither end of the molecule is “+” or “”. A Covalent bond is formed. Usually, less attraction exists between molecules and they can exist independently.
13
Inorganic Formulas and Nomenclature
Binary salts (metal + nonmetal) IONIC 1. Naming: prefixes used for giving the number of atoms of each element are NEVER used to name a salt. Name the first element (the metal) followed by the second element with the -ide suffix. 2. Examples: CaCl2 calcium chloride MgO magnesium oxide Al2S3 aluminum sulfide
14
Inorganic Formulas and Nomenclature
3. Writing formulas: the name will tell you what elements to write symbols for, but it will NOT tell you how many of each atom are present. Salts are always composed of cations and anions and charges must balance out in the formula. A shortcut is the “criss- cross” method to get the right formula. You can find the charges on the p-table if you have labeled it with “typical” charges. Calcium nitride; From the p-table 2+ 3- Ca N (6+) (6-) 3 2
15
Loss or gain of electrons by atoms leads to full, more stable energy levels as found in the noble gases (He, Ne, Ar, Kr, Xe, Rn). This loss or gain leads to the formation of cations and anions. 1+ 2+ 3+ 4+/- 3- 2- 1-
16
Inorganic Formulas and Nomenclature
4. Examples: strontium iodide SrI2 lithium oxide Li2O gallium arsenide GaAs
17
Rules for binary formulas:
Does name contain prefixes and 2 nonmetals? Yes…….. Write symbols FOLLOWED by prefix numbers as SUBSCRIPTS No……… Write symbols and look up cation/anion charges on p-table “criss-cross” charge numbers to become subscripts and reduce if possible

Quiz 1: Like Exercise 2-1 but you will also have to write formulas!
UE Book Quiz #1 Quiz 1: Like Exercise 2-1 but you will also have to write formulas! Quiz 2: You will write formulas ONLY!
26
Transition metals with variable charge
Note: several elements outside the “transition metal” columns carry more than one charge….see page 14 in UE handbook for these This table shows some of the oxidation states found in compounds of the transition-metal elements. A solid circle represents a common oxidation state, and a ring represents a less common (less energetically favourable) oxidation state.
27
Handbook Ch. 3 = 7+ KMnO4 2-(4) = 8- 1+ ?
Many element charges (oxidation states) can vary when combined with two or more elements. NOTE: the charges you have labeled on your periodic table are the MOST COMMON for BINARY SALTS ONLY! The formula below is NOT a binary salt! To determine the charge of one element, use the common charge of the other elements: KMnO4 2-(4) = 8- 1+ = 7+ ?
28
Handbook Ch. 3 Determine unknown charge from KNOWN charges, look at your periodic table! Be careful with parentheses: Mg(BF4)2 2+ 4(1-) x 2 = 8- The B would have to = 3+ (x2 = 6+)
29
Metals with variable charge…handbook Ch. 3
Many transition metals and metals such as tin and lead exhibit multiple valences; they can have more than one positive charge. Stock system (older) was a way of identifying which charge was present. NOTE TYPO ON GREEN SHEET! 3+ Fe is ferric Fe is ferrous 2+
30
Metals with variable charge
In the newer system, roman numerals are used in the name to indicate the charge of the metal cation: 2+ Fe is iron(II) Fe is iron(III) 3+
31
Metals with variable charge
One can always determine the charge of a transition metal in a compound by knowing the charge of the other element. What is the charge of the copper cation, +1 or +2? 2- Charge ? We know from the p-table that oxygen is a 2- CuO “copper (II) oxide” What would the charge of the copper have to be to “balance” the oxygen? 2+
32
Metals with variable charge
3+ 2- FeS 2 3 Which iron is it? Iron(II) or Iron(III)? Figure it out from the nonmetal (sulfur). You can also criss-cross from the bottom up. SEE PAGE 14 FOR LIST!
33
When naming compounds, ask……
Is the first element a nonmetal? If yes, use prefixes and end in –ide If no, is it a metal from page 14? If yes, use a roman numeral in the name for the charge of the element and end in –ide. If not on page 14, it is an ionic salt, name it with an –ide ending.
34
When writing formulas, ask……..
Is the first element a nonmetal? If so, use the prefixes in the name to write formula. If the first element is a metal followed by a roman numeral in parentheses, the roman numeral is the charge of the metal. Cross this charge with the nonmetal charge. If the first element is a metal NOT followed by a roman numeral, look up and cross the metal/nonmetal charges.
35

Quiz 2 from Ch. 1-4 Handout This quiz will be much like exercises 3-1, 3-2 and 3-3[3-2 (3, 4, 9, 16) and 3-3 (1, 14)] You will determine the charge of elements by deduction. (3-1) You will name transition metal salts by writing the metal name first followed by a roman numeral (unless it is silver or zinc) then the nonmetal with the ending –ide. 3-2 (3, 4, 9, 13-16, 19, 20) USE PAGE 14! You will write the formulas of transition metal salts by listing the metal symbol followed by the nonmetal symbol with their charges canceling out as subscripts (criss-cross). Remember that the roman numeral in the name is the charge of the transition metal. 3-3 (1, 2, 5, 9, 14, 17) NOTE: ALL CHEMICAL NAMES AND FORMULAS ON THIS QUIZ WILL BEGIN WITH A METAL FROM PAGE 14(MUST USE ROMAN NUMERAL IN NAME): I, II, III, IV, V, VI, VII, VIII, IX, X
55
Polyatomic ions MnO 4 1- “leftover” 7+ 2-
Some elements combine to form ions, not molecules. These are called polyatomic ions. See page 16. When they react, they form ternary compounds. Note page 16 in handout and reference sheet. Nearly all of these end in –ate or –ite. Poly anions/cations by charge and those which end in -ide Permanganate ion: 1- “leftover” MnO 4 7+ 2-
56
Polyatomic ions ClO4 perchlorate ClO3 chlorate ClO2 chlorite
These groups of atoms behave as single ions. There is no simple way to learn these, other than seeing the patterns in their families. For example, Cl and O can be “parent” ions…… see page 16 ClO4 perchlorate ClO3 chlorate ClO2 chlorite ClO hypochlorite # of oxygen atoms
57
Oxygen “family” of ions
Oxide = O2 Peroxide = O22…..each “O” is a 1- Superoxide = O21…one “O” is neutral and one “O” is a 1- Hydroxide = OH1−…“O” is 2- and H is 1+
58
Organic ions Carbon atoms are the “central” atoms with surrounding hydrogen and oxygen atoms: Can be written CH3COO or C2H3O2 (Acetate ion)
59
Ternary formulas and names….. I do, we do
When naming, simply use the periodic table and page 16 to combine the names of the element or ion(s). NEVER CHANGE THEIR SUFFIX ENDINGS! ALSO USE REFERENCE TABLE “POLYATOMIC IONS” MgCO3 Magnesium carbonate Cu(OH)2 Copper(II)hydroxide NH4Cl Ammonium chloride
60
Ternary formulas and names
When writing formulas, look up the symbols and charges of the element or ion(s) and cross them. Use parentheses if necessary: Iron(II)phosphate Fe3(PO4)2 Potassium sulfate K2SO4 Sodium hypochlorite NaClO
61
More I do….we do Na3PO4 2. aluminum hydroxide
CuSO potassium benzoate NH4F 6. zinc acetate CaC rubidium carbonate 9. LiOH iron(III)bicarbonate
62
Naming Ternary compounds (3 or more elements)
First element will be a metal or NH4+ If metal is not a transition metal (group 1 or 2) name the metal followed by the polyatomic ion name. If metal is from group 3-16, check to see if it is on page 14. If not, name as above. If on page 14, name metal followed by its charge in roman numerals and then name the polyatomic ion.
63
Formulas of ternary compounds
Look up metal symbol and charge from p-table or use roman numeral if present. Look up polyatomic ion formula and charge. Cross metal charge # to make subscript for poly ion, cross poly ion charge # to make subscript for metal. Reduce charge # if possible.
64
Exercise 3-2 on white sheet
You do… 3-2: 1, 2, 5, 6, 7, 8 / 10, 11, 12, 17, 18, 21 3-3: 3, 4, 6, 7, 8, 10 / 11, 12, 13, 15-20
65
Hydrated salts If first dissolved in water, many salts will “take-up” water molecules in their crystals as the water is evaporated. Their chemical formulas and names will indicate this in the following ways: Na2B4O7 • 10 H2O is sodium tetraborate decahydrate, or “borax” CaSO4 • 2 H2O is calcium sulfate dihydrate, or “gypsum” CuSO4 • 5H2O is copper (II) sulfate pentahydrate
66
Summary of Handbook Ch. 2 and 3
Determining whether or not the first element in the compound is a metal or nonmetal is the most important question. Apply the rules from there. When naming compounds that contain a transition metal (page 14) with variable charge as the first element, use roman numerals to indicate valence. When naming compounds that contain 3 or more elements, a polyatomic ion is present, use page 16 or reference sheet.

H2O(l) + HCl(g) ↓ H3O+(aq) + Cl-(aq)
Acids-notes for Ch. 4 Contain “ionizable” hydrogen ions, H+ When dissolved in water, some or all of the H+ ions separate from the anions and combine with water to form the acidic hydronium ion, H3O+ H2O(l) + HCl(g) ↓ H3O+(aq) + Cl-(aq) The hydrogen monochloride gas, when aqueous, is called hydrochloric acid
86
Acid Nomenclature…handbook ch. 4
Acids and Salts; Acidic compounds contain H+ ions in solution (aq), basic compounds contain OH in solution. When acids and bases react, they form water and a salt, either binary or ternary. HCl + NaOH HOH + NaCl Acid Base Water Salt
