What does Na2S formula mean?; What is the two in Na2S called?; How do you write Na2S?; What state of matter is Na2S?
xxTIMURxx [149]

The chemical compound sodium sulfide has the formula Na2S. It is written as Na_{2}S. It has a crystalline state. Na is followed by a two or 2. this indicates that the molecule has two of the specified element's atoms.

There is just one of these because there is no number following the S.

In all, this molecule consists of one sulfur atom and two sodium atoms.

A compound's chemical formula, which uses symbols for combining atoms, reveals the composition of the complex. We require the valency of the combining parts in order to write the formula.

The sodium sulfide chemical formula must be written down. So sodium and sulfur make up the two elements in the chemical. Sodium has a valency of +1, while sulfur has a +2.
