Explanation:
Detailed explanation-1: -When these atoms gain electrons, they acquire a negative charge because they now possess more electrons than protons. Negatively charged ions are called anions.
Detailed explanation-2: -One coulomb consists of 6.24 × 1018 natural units of electric charge, such as individual electrons or protons. From the definition of the ampere, the electron itself has a negative charge of 1.602176634 × 10−19 coulomb.
