How do ions form electrically neutral compounds.

Hint: Ions are electrically charged particles; they can be negatively charged ions or positively charged ion. Charge of ions depends on sharing during bond formation. The overall ionic formula for a compound must be electrically neutral, meaning it has no charge to be an electrically neutral compound.

Complete step-by-step answer:
Ions form electrically neutral compounds by sharing the charge. A electrically negative change ion and positive charge ion form ionic bonds between them during this bond formation they share their electron to neutral them and to form an ionic bond. For example, in the reaction of calcium with chlorine, the compound form is called calcium chloride.

 It is composed of $C{a^{ + 2}}$ cations and $C{l^ - }$ anions; these ions are stable till they have filled valence shells. Its ionic formula is written as $CaC{l_2}$, the neutral combination of these ions. Salts are electrically neutral (of course all matter is electrically neutral). If the species have an anion, there must be cations so that they can balance the charge.

Note: Covalent bonded compound are also electrically neutral compound but these organic neutral compound cannot get their charge back in aqueous solution, while ionic bonded electrically neutral compound get their charge back in their aqueous solution or the ions dissociate again with their respective charges.
