Explanation:
Ions are the species that contain a charge either positive or negative charge.
When a neutral atom loses an electron then it acquires a positive charge. Whereas if a neutral atom gains an electron then it acquires a negative charge.
For example, [tex]Na^{+}[/tex] means there is +1 charge on sodium.
But if a compound does not contain any charge then it means the compound is neutral.
For example, in the compound [tex]P_{4}O_{6}[/tex] there is no charge so, this compound is neutral.
Hence, we can conclude that no ions are present in a sample of [tex]P_{4}O_{6}[/tex].
