NOTES ON METALS. NONMETALS, AND METALLOIDS 1. METALS = SHADED IN SILVER-SKETCH AND SHADE TABLE

METALS 2. Metals are generally located on the left side of the zigzag line. 3. Examples of metals are: Sodium (Na), Calcium (Ca), Iron (Fe), and Aluminum (Al). 4. The majority of elements are metals.

5. NONMETALS= SHADED IN RED-SKETCH AND SHADE

NONMETALS 6. Nonmetals, with the exception of Hydrogen (H), are located on the right side of the zigzag line. 7. Examples of nonmetals are: Chlorine (Cl), Oxygen (O), Sulfur (S), and Iodine (I).

8. METALLOIDS=SHADED IN YELLOW- SKETCH AND SHADE

METALLOIDS 9. There is a zigzag line on the right side of the periodic table that separates the metals from the nonmetals. Metalloids are found on the zigzag line. 10. Elements identified as metalloids have properties (characteristics) of both metals and nonmetals.

Wednesday

Bell Ringer 9-23  Metals Verses Nonmetals  Complete the t-chart to contrast metals and nonmetals. Metals Vs Nonmetals 1. Vs1. 2. Vs2. 3. Vs3.

Discussion  Copy and Discuss- Notes on "Chemical Symbols and Formulas" found on the next few pages.

Notes on "Chemical Symbols and Formulas"-Keep in notebook  Symbols 1. A chemical symbol is a shorthand name for an element. 2. Each element on the periodic table is represented with a unique symbol. 3. A symbol may be made of 1, 2, or 3 letters. 4. The first letter of each chemical symbol is always capitalized.

REVIEW THESE QUICKLY---"Chemical Symbols"- YOU SHOULD ALREADY HAVE THEM IN YOUR NOTEBOOK. ElementSymbolElementSymbol HydrogenHSiliconSi CarbonCCopperCu NitrogenNAluminumAl OxygenOSilverAg ChlorineClGoldAu MagnesiumMgIronFe ZincZnHeliumHe CalciumCaPotassiumK PhosphorusPSodiumNa

Notes on "Chemical Symbols and Formulas"- Keep in notebook  CHEMICAL FORMULAS  5. Chemical formulas use element symbols from the periodic table and numerical subscripts to depict the name and number of atoms of each element in the compound; examples include: Water (H2O), Glucose (C6H12O6), and Table Salt (NaCl).

Notes on "Chemical Symbols and Formulas"- Keep in notebook  6. In a chemical formula, the numbers as subscripts show how many of each kind of atom are in the compound.  7. The subscript is written to the lower right of the element symbol.  8. The subscript in CO2 is the #2. There are 2 atoms of oxygen present in CO2.

Notes on "Chemical Symbols and Formulas"- Keep in notebook  9. If no subscript is written, only one atom of that element is part of the compound.  10. There is an invisible 1 after the C. So, there is only 1 atom of carbon present in CO2. ***SCIENTISTS DO NOT WRITE THE INVISIBLE 1 BECAUSE IT IS UNDERSTOOD TO ALREADY BE THERE. ***

Notes on "Chemical Symbols and Formulas"- Keep in notebook  11. For example, in H2O, the number 2 is the subscript for hydrogen and means that there are 2 atoms of hydrogen in the compound of water; since there is no subscript for oxygen it is assumed to be one atom of oxygen.

Notes on "Chemical Symbols and Formulas"- Keep in notebook  12. N2, O2, F2, Cl2, Br2, I2, and H2 are diatomic molecules where all of the atoms of the molecule are the same element.

Notes on "Chemical Symbols and Formulas"- Keep in notebook  Ionic Bonds  13. Ionic bonds are formed when metals and nonmetals chemically bond to form a new substance.  14. In ionic bonds, electrons are transferred from the metals (SILVER) to the nonmetals (RED).

Notes on "Chemical Symbols and Formulas"- Keep in notebook  Covalent Bonds  15. Covalent bonds are formed when nonmetals bond with other nonmetals. (RED AND RED)  16. In covalent bonds, electrons are shared.
