GENERAL KNOWLEDGE

Detailed explanation-1: -Therefore, an atom that loses electrons becomes a positively-charged ion called a cation.

Detailed explanation-2: -Atoms that lose electrons acquire a positive charge as a result because they are left with fewer negatively charged electrons to balance the positive charges of the protons in the nucleus. Positively charged ions are called cations. Most metals become cations when they make ionic compounds.

Detailed explanation-3: -Cations and anions are charged species which are formed by losing and gaining electron(s) respectively to attain the nearest noble gas configuration or stability. Usually metals lose their valence electrons to form cations while non-metals accept electrons and form anions.

Detailed explanation-4: -Thus, to attain the noble gas configuration, a nitrogen atom would tend to gain 3 electrons. As a result of this, the ionic charge on nitrogen would be 3-. Thus, nitrogen gain electrons, and its ion exists as N3− .

Detailed explanation-5: -To become a positive ion, a neutral atom must lose an electron. Neutral atoms gain their neutrality by having an equal number of protons and electrons, the two charged subatomic particles in an atom. The positive charge of a proton is equal to the negative charge of an electron so they cancel each other out.
