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.

Atoms 1, 3, 5, 7 and 9 are all one element; 2, 4, 6, and 8 are all the same different element.

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.
