6. Know atomic structure –

nucleus contains ______(+) and ______(0)

shells or cloud contains ______(-)

7. Understand that atoms are the building blocks of matter. There are 118 different atoms. Each type of atom has different number of protons- that is what makes them different! These are the elements and they are listed on the periodic table. Be able to use the periodic table.

Ag = ______Ne = ______

Electrons = # of protons

9. Be able to identify or use a Bohr’s Model of an atom

10. Understand that atoms that are chemically bound (stuck together) form molecules of a compound. The compound has NEW chemical and physical properties that are different than the elements that it is made up of.

H20 = H- hydrogen 2 atoms O-Oxygen 1 atom

NaHCO3 = ______

10. A chemical formula is an equation that shows what substances you start with (reactants) and what substances you end with (products) in a chemical reaction. The equation must be balanced with the same number of atoms of each element on each side.

___+Na + ____ Cl2  ____ NaCl

11. Know the difference between a substance and a mixture (homogeneous and heterogeneous)

12. Know the basic difference between an acid and a base

13. Law of Conservation of Matter states that matter can not be created nor destroyed only
