Elements in the same period have the same number of electron shells; moving across a period (so progressing from group to group), elements gain electrons and protons and become less metallic. Roger Duthie offers his experience and insights on the sports industry reactivating. See abstract, Bearden, J. (CC BY-SA- 3.0; from NikNaks). This is because, with increasing principal quantum number, electrons get further away from the nucleus creating a shielding effect felt by those electrons from the electrons closer to the nucleus. Oxford: Butterworth-Heinemann, 1997. What is effective nuclear charge of chlorine? Argon has an atomic number of 18 and a shielding electron number of 10 (electron configuration of {eq}[Ne] 3s^2 3p^6 {/eq}).
