- Is a force between atoms that share valence
electrons

5Diatomic Moleculesmade of 2 identical elements
with a covalent bond

6They occur in nature this way becausethey are

If there is only one atom of the first element,
DO NOT use a prefix

13Step Two
Name the second element and change the ending to
-ide

20Polar Covalent Bonds
- Result from an unequal sharing of electrons
21To be or Not to be?
- Polar
- Subtract the electronegativities of the bonding
elements
