As you move across an element period (row), the overall size of atoms decreases slightly. Data taken from John Emsley, The Elements, 3rd edition.Oxford: Clarendon Press, 1998. The ionization energy of the elements increases as one moves up a given group because the electrons are held in lower-energy orbitals, closer to the nucleus and thus more tightly bound (harder to remove). There are some systematic deviations from this trend, however. Tags: Question 40 .
