Explain Ion Formation Practice Test

N gains 5 electrons because it has 5 valence electrons, forming N⁵⁻ to become stable.

N loses 5 electrons so that it has 2 valence electrons, forming N⁵⁺ to become stable.

N loses 3 electrons to complete an octet and reach a noble gas configuration like He, forming N³⁺.
