Balanced! Formula is: KCl
Ca 2+ Formula is: CaBr 2 Br - Not balanced! 1(2+) + 2(1 - ) = 0
Ca 2+ S 2- Formula is: Ca 2 S 2 Reduce!! Formula is: CaS Correct!!
If an element forms more than one ion, a Roman numeral is used to indicate the charge
Zinc = Zn 2+ Silver = Ag + No Roman numeral is used for elements that have only one oxidation state
Fe 3+ O 2- Not balanced! Formula is: Fe 2 O 3 2(3+) + 3(2-) = 0
Fe 3+ O 2- Fe 2 O 3
Ca 2+ NO 3 - Ca ( NO 3 ) 2
Li + CO 3 2- Li 2 CO 3
Mg 2+ OH - Mg(OH) 2
Ionic Compound Formulas IonsIons Cation: A positive ion Mg 2+, NH 4 + Anion: A negative ion Cl , SO 4 2 Cation: A positive.
12 Weeks to TAKS Week 11 Part II 12 Weeks to TAKS – Week 10 Objective 4: IPC 7D: The student is expected to relate the chemical behavior of an element.
Ionic Compound Formulas
Topic: Polyatomic Ions Do Now: p.12. Potassium (K) and Fluorine (F) Zinc (Zn) and Iodine (I) Sodium (Na) and Oxygen (O) Magnesium (Mg) and Oxygen (O)
Topic: Polyatomic Ions Do Now: Review, write the binary ionic formula for: Potassium (K) and Fluorine (F) Zinc (Zn) and Iodine (I) Sodium (Na) and Oxygen.
Ionic Compound Formulas IonsIons Cation: A positive ion Mg 2+ Anion: A negative ion Cl Cation: A positive ion Mg 2+
Ionic Compounds Binary compounds: compounds composed of two elements Binary Ionic Compounds Made up of what types of elements? Ex. KCl Contains: potassium.

Ionic Formulas Turning chemistry into algebra. REVIEW We can tell how many electrons an atom will gain or lose by looking at its valence electrons. Metals.
COMPOUNDS chemical combination of two or more different elements chemical combination of two or more different elements two types: two types: IONIC IONIC.
Properties of Ionic Compounds Forming NaCl from Na and Cl 2 A metal atom can transfer an electron to a nonmetal. A metal atom can transfer an electron.
Ionic Bonding (Part III) Slightly More Complex Ionic Compounds.
IONS AND THEIR COMPOUNDS. REMEMBER HOW WE CAN PREDICT ION CHARGES FROM THE PERIODIC TABLE.
Names and Formulas for Ionic Compounds Part 1. Types of ions Monatomic ion – ion with one atom Mg 2+ magnesium ion Cl - chloride ion Polyatomic ion –
