The metals group 2 from top to bottom are $B e, M g, C a, S r, B a$

(ii) State the common feature in their electronic configuration.

Open in App

Solution

Since all the atoms $B e, M g, C a, S r,$ and
$B a$ belong to the same group 2. Therefore, they possess the same number of valence electrons and valency that is 2.
