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

29. 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.

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

31. 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).

32. 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.

33. 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. ***

34. 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.

35. 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.

36. 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).

37. 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.
