GENERAL KNOWLEDGE

Detailed explanation-1: -Thus, when an atom gains electrons, it becomes negatively charged.

Detailed explanation-2: -Thus, an atom that gains electrons becomes a negatively-charged ion called an anion.

Detailed explanation-3: -When these atoms gain electrons, they acquire a negative charge because they now possess more electrons than protons. Negatively charged ions are called anions. Most nonmetals become anions when they make ionic compounds.

Detailed explanation-4: -Whenever there is a gain of electrons the element will acquire a negative charge also known as an anion while when an atom loses an electron, the element acquires a positive charge which is also known as a cation.

Detailed explanation-5: -As opposite charges attract, negatively charged electrons are drawn to positively charged protons. Electrons are referred to as negative because of their behavior in an electric field. In an electric field, an electron will move from the negative pole to the positive pole, giving it a negative charge by convention.
