To write the formula for sodium sulfide, you need to know the elements involved and their charges. Sodium (Na) has a charge of +1, while sulfide (S) has a charge of -2.

Steps to Determine the Formula

Identify the elements: Sodium and sulfur.
Determine their charges: Sodium is +1, and sulfide is -2.
Balance the charges: To balance the +1 charge of sodium, you need two sodium ions for each sulfide ion.

Final Formula

Putting it all together, the formula for sodium sulfide is Na₂S. This indicates that there are two sodium ions for every one sulfide ion in the compound.
