WebPeriod Trends. There are many trends on the periodic table. For example, ionization energy, electronegativity, and of course atomic radius which we will discuss now. Across a period, atomic radii decrease. This is because while the number of electrons increases down the period, they only add to the same main energy level, and therefore do not ... Web$\begingroup$ Consider the size of the first s-orbital of $\ce{Mg}$. The nuclear charge is 12+. Therefore the first electrons, close to the nucleus, are attracted by a relatively large force. These first electrons the 'shield' the nucleus from some of the charge when adding more electrons to the orbitals, these latter electrons experience a smaller charge than …
