WebJan 30, 2024 · Electron affinity increases upward for the groups and from left to right across periods of a periodic table because the electrons added to energy levels become closer to the nucleus, thus a stronger attraction between the nucleus and its electrons. WebAs shown in Figure 6.31, as we move across a period from left to right, we generally find that each element has a smaller covalent radius than the element preceding it.This might seem counterintuitive because it implies that atoms with more electrons have a smaller atomic radius. This can be explained with the concept of effective nuclear charge, Z eff.

Explanations for atomic trends going across a period ( )

WebIonic radii decrease across a period. This is due to the fact that metal cations lose electrons, causing the overall radius of an ion to decrease. Non-metal cations gain electrons, causing the overall radius of an ion to decrease, but this happens in reverse (compare fluorine to oxygen and nitrogen, which one gains the most electrons). WebAs you move across a row of the periodic table, the ionic radius decreases for metals forming cations, as the metals lose their outer electron orbitals.
