How the valency of barium is 2?
Barium is an alkaline earth metal that has 2 outer electrons in its 6s shell. Like the other metals in this group, it readily loses these electrons to form a Ba 2+ ion. So, barium has a theoretical valency of 2, and it actually has this valency in BaCl2 and BaSO4.
Why does barium have 2 valence electrons?
This electron configuration shows that the last shell of barium has two electrons. Therefore, the valence electrons of barium are two. The elements that have 1, 2, or 3 electrons in the last shell donate the electrons in the last shell during bond formation.
