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?
