1. When atoms form an ion, describe the outer shell of that ion.
2. Draw the following Bohr Model Diagrams (NOTE THEY ARE IONS)
Be 2+
ClFN3-
Ca2+
K+
Na+
O2-

3. Draw the following compounds (remember that these compounds must
become ions before they are bonded to each other)
Compound
Bohr Model
NaCl
KF
BeO
MgS
4. If a new element has seven valence (Outer) electrons, which column of
the periodic table should it be placed in?
5. If a new element is discovered that has two outer electrons, in which
column or group should it be placed in?
6. Do noble gases make ions? Why or why not?
