Sulfate consists of 1 S, and 4 O and so has a charge of 2-. You can see this directly from the Periodic Table by checking what group these atoms are in. Sulfur and Oxygen are both in the 6th group, meaning they both have 6 valence electrons. So (6 electrons * 5 atoms) = 30 electrons. If we follow the octet rule (each atom must have 8 valence electrons for a full octet), then we need 2 more electrons. Sodium, Na, is in the 1st group on the periodic table, and therefore has 1 valence electron. So we need 2 sodium atoms, giving us the formula:
Na2SO4
That is,
2 Na
1 S
4 O
It's important to remember that when atoms 'share' their electrons by bonding, that BOTH atoms 'see' the electrons as theirs, meaning that, for example, although you may have 14 electrons between 2 atoms, as long as there is a single bond between the atoms they will both have full octets.
For example: O2
:::O:O:::
where : = pair of electrons.
