WebTrends in Period Three of the Periodic Table. Groups I, II and III are metals and so metallic bonding is used. Group IV is a macromolecule and so has a very large melting point. Groups V, VI, VII are molecules and so we rely on temporary dipole-dipole attractions. Phosphorus is P 4 and so has a reasonably large temporary dipole. Weband the atomic radius decreases.

"Webhey guys, quick question on Period 3 elements and the Electron affinity. i know that electron affinity increases across period 3 because. 1. the radius slightly decreses while the nuclear charge increases and so the atom reaches maximum stability. however, in data tables the electron affinity (ini kJ/mol) goes like this. Na = 53. Mg = 0. Al = 42. " - Trend across period 3

In the whole of period 3, the outer electrons are in 3-level orbitals. These are all the same sort of distances from the nucleus, and are screened by the same electrons in the first and second levels. The major difference is the increasing number of protons in the nucleus as you go from sodium across to argon.

WebTrends. IE increases across period from left to right. This is because since electrons are pulled closer to nucleus (see atomic radius), more difficult to remove them. IE decreases down a group from top to bottom. This is because atomic radii increase down group, making easier to remove electron.
