The melting points of group \(13\) elements do not follow a regular pattern, as elements from groups \(1\) and \(2\) do. This is most likely due to the peculiar crystal structures of B and Ga. Actually, as one moves down the group from B to Ga, the melting points decrease sharply and then increase from Ga to Tl. WebSep 22, 2024 · The outer electronic configuration of group 13 elements is n s 2 n p 1. In this, Boron and Aluminium have noble gas cores. Gallium and Indium have noble gas cores plus 10 d electrons. Thallium has a noble gas. core plus 14 f electrons plus 10 d-electrons. This difference in electronic structure results in different properties and chemistry. hairstyle for older ladies with thin hair
