Use your periodic table to identify the name for each element in a compound

... where is the image??

Here is an example though:
If you were given NaCl (this is he chemical formulafor table salt) you could identify Na (first column, or group, on your periodic table (PT) and 2nd row, or period, on your PT) as sodium.
The Cl you could identify as Chloride.

They are all full and don't need any more electrons in there outer shell.
