RE:
What is the formula for Sodium Sulfide?

Phys is correct.
Sodium (Na) is 1+
Sulfide is 2-
in order for the electrons to be equal, you must have twice as many sodium molecules, therefore
Na2S

Sodium sulfide is the name used to refer to the chemical compound Na2S but more commonly its hydrate Na2S.9H2O. Both are a colorless water-soluble salts that give strongly alkaline solutions. When exposed to moist air, Na2S and its hydrates emit hydrogen sulfide, which smells much like rotten eggs.

2- the sodium has a charge of 1+ and there are two of them which gives 2+ the molecule is neutral so this charge must be balanced compleatly by one sulphur. therfore the sulphur must have a 2- charge.

Sulphur is -2 and Sodium is +1, so there are two sodium atoms and one sulphur atom.
Sulphur is S and Sodium is Na.
You take it from there. :)

Hydrate is Na2S. 9H2O (normally occurring)
Anhydrous is Na2S
Industrially Na2S is produced by reduction of Na2SO4 with carbon, in the form of coal:
Na2SO4 + 4 C → Na2S + 4 CO
