Question

If the valence electrons were removed, what would be the ion charge of the element?


Al

Answer 1

Depends on how many you remove.

Removal of one electron (1)
Al+
Removal of two electrons (2)
Al++
Removal of three electrons (3)
Al+++
Removal of all valence electrons would result in an electron configuration similar to that of Neon.

1s^2 2s^2 2p^6 3s^2 3p^1
1s^2 2s^2 2p^6 3s^2 one electron
1s^2 2s^2 2p^6 3s^1 two electrons
1s^2 2s^2 2p^6 there electrons
The last configuration is that of a noble gas hence most stable.

Answer 2

Al 3+
