GENERAL KNOWLEDGE

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

Detailed explanation-2: -If an atom loses or gains electrons, it will become a positively or negatively charged particle, called an ion. The loss of one or more electrons results in more protons than electrons and an overall positively charged ion, called a cation.

Detailed explanation-3: -If an atom loses electron it forms positive charge and if gains electron it forms negative charge. An atom which carries charge on it is known as ion.

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: -Metals tend to lose electrons and form positively charged ions called cations. Non-metals tend to gain electrons and form negatively charged ions called anions.
