Valency (in chemistry) is the number of the valence bonds of a chemical element.
Iron has two electrons in the outa shell meaning that it has a valency of +2 Lewis is awes!!!
valency of lithium - 1
valency of Rf =4 valency of Db=5 valency of Sg=6 valency of Bh=7 valency of Hs=8 valency of Mt=unknown
-1 valency
The valency of sulfur is 2-. The valency of sulfur is 2-. The valency of sulfur (S) is +2
The valency of sodium is +1
PO4 has its valency 3 but, PO3 also has its valency 3
Its valency is 0.
the valency is 4
+4 valency
+3 valency
Valency = 2 -
