Question

State whether the statement is True or False:

$A{l}^{+3}$ is less stable than $Al$.

Answer 1

Electronic configuration of Al $\Rightarrow$ $1s^2,2s^{2}2p^6,3s^{2}3p^1$.

Thus we can say that the valency of Al is 3. It is stable in it's + 3 states as after loosing 3 valence electrons it will get the stable configuration of noble gas-

Ne $\Rightarrow$ $1s^2,2s^{2}2p^6$

So, $A{l}^3+$ is more stable than Al.

Hence, the given statement is false.
