# Solution: A portion of a two-dimensional "slab" of NaCl(s) is shown here in which the ions are numbered.Which colored balls must represent sodium ions?

###### Problem
A portion of a two-dimensional "slab" of NaCl(s) is shown here in which the ions are numbered.

Which colored balls must represent sodium ions?

###### Solution

We have to determine which colored balls represent sodium ions in the given diagram for NaCl.

An ionic compound is made from a cation and an anion.

A cation is formed by the loss of electrons from a neutral atom while an anion is formed by gain of electrons by a neutral atom.
