1 (in most of the compounds)
the valency of iodine is 7.
Iodine's atomic number is 53. That puts it in the halogen group. All halogens have 7 valence electrons.
Bromine is a non-metal and a part of the halogen family. Other members of this family are Chlorine, Fluorine, Iodine and Astatine. So, like other members of this family, Bromine has a valency of 1.
-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

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
No, it is due to them having the same number of valency electrons.
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
+3 valency
Its valency is 0.
the valency is 4
