Answer 2

Answer:

Beta

Calcium has an electronic configuration ends at 3s^2

And it is easy to eject the electron from this orbital

So it will get a charge of 2

And it is positive 2 beause the lost 2e was making the neutrality of the parent atom

Since 2 negetive charge is removed, and the nuclear charge is intact. It will get +2

As well as same case in al+3

Down the gp stability of +3 decreases due to inert pair effect and Al is in some what top +3 is stable

Ask if there is doubt

Follow me if u are convinced
