GENERAL KNOWLEDGE

Detailed explanation-1: -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-2: -When an atom loses or gains an electron, ions are formed. 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-3: -Nonmetals form negative ions (anions). A nitrogen atom must gain three electrons to have the same number of electrons as an atom of the following noble gas, neon. Thus, a nitrogen atom will form an anion with three more electrons than protons and a charge of 3−.

Detailed explanation-4: -An atom becomes an ion when it gains or loses electrons. The ions that are formed when an atom loses electrons are positively charged because they have more protons in the nucleus than electrons in the electron cloud. Positively charged ions are called cations (pronounced CAT-ions).

Detailed explanation-5: -If an atom gains an electron, the ion is called an anion due to the overall negative charge on the atom. Anions have more electrons than protons, which causes the overall negative charge on the atom.
