Answer:

Explanation:

Magnesium is the element of second group and third period. The electronic configuration of magnesium is - 2, 8, 2 or $1s^22s^22p^63s^2$

There are 2 valence electrons of magnesium.

Fluorine is the element of seventeenth group and second period. The electronic configuration of fluorine is - 2, 7 or $1s^22s^22p^5$

There is 1 valence electron of fluorine.

They will combine and form $MgF_2$

<u>The same type of compound is formed by the other members of the group 2 since they will have 2 valence electron.</u>

Group 2 includes:- beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).

Hence, correct options is:- Ba
