Ions also have electron configurations (Section 7.4). Cations have fewer valence electrons, and anions have more valence electrons, respectively, than their parent atoms. For example, chloride, Cl–, has an electron configuration of 1s22s22p63s23p6, for a total of 18 electrons, compared to 17 for neutral chlorine, the element. Na has an electron configuration of 1s22s22p63s1, but Na+ has an electron configuration of 1s22s22p6 Write out the electron configurations for (d) K+,
