Sodium Sulfide (Na₂S): Chemical Formula & Explanation

Science >> Science Discoveries > >> Chemistry

The chemical formula for sodium and sulfur is Na₂S.

Here's why:

* Sodium (Na) has a +1 charge when it forms an ion.

* Sulfur (S) has a -2 charge when it forms an ion.

To balance the charges, you need two sodium ions (+1 each) to combine with one sulfur ion (-2). This gives you a neutral compound with the formula Na₂S.
