  1. Counting Atoms, Naming, and Bonding So…this is chemistry.

  2. Classification of Elements • Uses position on the periodic chart (dictated by how the element acts) to tell what the element “is” • We already did this with the coloring of the chart

  3. Valence electrons • The number of electrons in the outermost shell • Tells a bit about how it will react • Can tell by position on the periodic chart

  4. Counting Atoms • So two elements combined makes a compound. There is bonding involved. • You need to COUNT the number of each type of atom in a compound • You can tell this from the formula

  5. Some more examples Magnesium fluoride (MgF₂) Sodium chloride (NaCl) One atom of Sodium One atom of Chlorine • One atom of Magnesium • Two atoms of Fluorine

  6. You can name compounds based on what they are made of • Mono - 1 • Di - 2 • Tri - 3 • Tetra - 4 • Penta - 5 • Hexa - 6 • Hepta - 7 • Octa - 8 • Nona - 9 • Deca - 10

  7. Some examples… • Nitrogen oxide • Dinitrogen oxide • Nitrogen dioxide • Dinitrogenpentoxide • Dinitrogen trioxide

  8. So let’s try counting a few… • H₂O • LiF • K₂S • H2SO4 • CH4 • C8H10N4O2

  9. Another complication… • 2 K₂S • 3 H₂O • 4 H₂SO₄

  10. Yet another wrench… • 3 Ca(NO3)2 • 2 Fe(NO3)2 • 5 BaSO4
