Detailed explanation-1: -electron, lightest stable subatomic particle known. It carries a negative charge of 1.602176634 × 10−19 coulomb, which is considered the basic unit of electric charge.

Detailed explanation-2: -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.

Detailed explanation-3: -On the atomic level, protons are positively charged and electrons are negatively charged.

Detailed explanation-4: -An ion is an atom or group of atoms that has an electric charge. Ions with a positive charge are called cations. Ions with a negative charge are called anions.

Detailed explanation-5: -It is experimentally found that the charge of an electron is
