Some atoms have nearly eight electrons in their valence shell and can gain additional valence electrons until they have an octet . When these atoms gain electrons, they acquire a negative charge because they now possess more electrons than protons. Negatively charged ions are called anions.Feb 6, 2021
an octet
The octet rule is a chemical rule of thumb that reflects the theory that main-group elements tend to bond in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas.
