For example, calcium is a group 2 element whose neutral atoms have 20 electrons and a ground state electron configuration of 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2. When a Ca atom loses both of its valence electrons, the result is a ion with 18 electrons, a 2+ charge, and an electron configuration of 1 s 2 2 s 2 2 p 6 3 s 2 3 p 6 .
