WebMar 23, 2024 · Valence electrons: For main group elements (i.e s-block and p-block elements), the valence electrons are the electrons present in the outermost orbit. But for most of the transition and inner transition elements, the valence electrons are the electrons present in the shells outside the noble gas core. WebJul 1, 2024 · 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.
