According to electronic configuration, configurations of condensed electrons of:
Ba = [Xe]6s2
Cl = [Ne] 3s23p
Ba elements with two valence electrons are found in group 2 of the periodic table, giving Ba a two-dot Lewis structure.
Chlorine atoms have seven valence electrons in their outermost shells; to complete their octet, they must gain one electron and one negative charge. When these two elements come together, ionic compounds are created.
BaCl2 is an ionic compound that is formed when Ba+2 and Cl 1 mix.
A metal from the second group of elements, barium always exhibits a +2 oxidation state. As a result, in Bacl2, Ba had a +2 charge that lost its electrons, while two chlorine atoms gained an electron with a -1 charge.
Thus formal Charge on Bacl2 = Ba =+2, and 2Cl= -1.
