Manganese is a transition element and has a variable valency but generally has a valency
of 2 and exists as Mn2+
Since O is 2- in valency and there are 2 O in MnO2, the O2 component represents a total valency of 4- (2 x 2 = 4). For MnO2 to be electrically neutral in this format, Mn must have a valency of 4+.
it is the stupidest compound whos valency is really difficult to find
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
+3 valency

PO4^-3 is an ion.So its valency is -3

Mercury
valency
The valency of an element measures its ability to combine with other elements. This valency is determined by the number of electrons in the outer shell of each atom of an element.
Permanganate Symbol is MnO4- Valency of the ion is -1, the manganese is +7 and the oxygen -2. Potassium Permanganate symbol is KMnO4.
The number of electrons in the outermost energy shell is usually used in finding the valency of a given element. For instance elements that have two electrons in the outermost energy shell have valency 2.
by knowing the no. of electorns in its outermost shell
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
