How is the valency of barium determined?

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. In fact barium always reacts with a valency of 2 in all of its compounds, and it is also very reactive. read more

So it’s electronic configuration is 2,8,8,8,8,8,8,6 Valency of barium=+2 Hope it helps!! This page may be out of date. Save your draft before refreshing this page. read more

Barium holds an atomic number of 56 with two electrons in its outermost shell. As these electrons are in the outermost shell they are ready to be lost. The electrons are dispersed throughout the orbitals under this configuration 1s22s22p63s23p63d104s24p64d105s25p66s2. read more
