Answer:
Gain 3 electrons.
Explanation:
If element X have 5 valence electrons it will more than likely gain 3 electrons to fill its octet to become stable. Gaining the 3 electrons is much easier for the atom than if it were to give away it's 5 valence electrons. Elements with 5 valence electrons that could represent element X are:
- Nitrogen
- Phosphorus
- Arsenic
- Antimony
