What is Sulphur?
The elements of this column in the periodic table has a consistent charge of +2.
What is column 2?
This is how you calculate the number of neutrons in an atom.
What is Mass number - # of protons?
CaCl2
What is Calcium chloride?
Silver Nitride
Ag3N
These compounds act as a single ion and has a charge.
What is a polyatomic ion?
These elements do not react with other elements because they already have a full valence shell.
