Properties Of Aluminium - Chemical Properties & …
What is Aluminium? Aluminium is a prominent “group 13” element, a meer of the Boron family. Electronic configuration of Aluminium is 1s 2 2s 2 2p 6 3s 2 3p 1. Due to an additional electron orbit in comparison to Boron, the sum of the first three ionization enthalpies of Aluminium is low in comparison to Boron and is, therefore, able to form Al 3+ ions.
