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. The rest mass of the electron is 9.1093837015 × 10−31 kg, which is only 1/1, 836the mass of a proton.

Detailed explanation-2: -Electrons: An electron is a subatomic particle that is negatively charged. 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.

Detailed explanation-3: -There are two kinds of electric charge, positive and negative. On the atomic level, protons are positively charged and electrons are negatively charged.

Detailed explanation-4: -A negative charge is an electrical property of a particle at the subatomic scale. An object is negatively charged if it has an excess of electrons, and is uncharged or positively charged otherwise. Such electrochemical activity plays a vital role in corrosion and its prevention.

Detailed explanation-5: -Answer and Explanation: A negatively charged atom is called an anion. Anions are usually formed when non metals accept additional electrons from metallic elements.
