Give an example of a formula of an ionic compound and explain why the formula is ionic. Please can someone help???

NaCl

The overall ionic formula for a compound must be electrically neutral, meaning it has no charge.

When writing the formula for the ionic compound, the cation comes first, followed by the anion, both with numeric subscripts to indicate the number of atoms of each.

ions are formed when metals are combined with nonmetals

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

plz give brainliest
