Question

Predict the number of each atom needed to form a molecule of potassium Sulfide.

Answer 1

2.0 atoms of K and 1.0 atom of S are needed to form a molecule of potassium sulfide.

Step-by-step explanation:

• The potassium sulfide has the chemical formula K₂S.

∴ Every 1.0 molecule of K₂S composed of 2.0 atom of K and 1.0 atoms of S.

So, 2.0 atoms of K and 1.0 atom of S are needed to form a molecule of potassium sulfide.
