hope it's helps you

Answer 2

Answer:

The formula for sodium sulfide is

N

a

2

S

.

Since this is an ionic compound, you must balance the charges so that overall charge of the compound is neutral.

Sodium, an alkali metal, has a tendency to lose one electron.

As a result sodium normally carries a positive one charge.

Sulfur, a nonmetal, has a tendency to gain 2 electrons.

This results in an ion with a negative 2 charge. Nonmetal ions end in "ide".

To obtain a neutral charge, you need two sodium ions, which provides you with a plus 2 charge balance the negative 2 charge of sulfur.
