Question

What is the most stable monatomic ion formed from aluminum?

Please help! and please explain your answer thanks! :)

Answer 1

Aluminum is group 13 or IIIA since the group number 12 has the number 3 is the 1st place, we would predict the change to be 3+ to give Al​3+

Answer 2

The most stable ion is
`Al^(3+)`

Step-by-step explanation:

The aluminium belongs to Group 13 of the periodic table. The elements of this group have 3 electrons of valence and due to the metalic characterictics the aluminuim has, it trends to lose those electrons to achieve stability.

Electrons are negatively charged (-1 each one), so when the neutral atom loses 3 of them it remains positively charged by +3
