Question

What is the electronic configuration of aluminum in Al2Cl6

Answer 1

The atomic number of Aluminium is 13 ,so its electronic configuration is 2, 8, 3 . It has 3 electrons in outermost shell . The aluminium atom can lose these 3 electrons to form the aluminium ion ,Al³+, having an inert gas electron configuration of 2,8. I2Cl6 – each iodine has 6 electron regions (octahedral) and only 4 bonding with the bonds taking a square planar shape so the molecules will be flat. Al2Cl6 – each Al will have 4 electron regions (tetrahedral) and 4 bonds so bonding around each Al is tetrahedral.
