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+.
The valency of Mn in MnO is +2. This is because oxygen has a valency of -2, so to balance the overall charge of the compound, manganese must have a valency of +2.
Manganese has the structure [Ar]4s23d5 and so the valence electrons in the valence shell are 4s23d5

The valency of lithium is 1. It has one valence electron in its outer shell.
The valency of silver is typically +1. However, silver can also exhibit a valency of +2 in certain compounds.
Carbon has a valency of 4, while sulfur has a valency of 6.

False. If ABC definitely equals DEF equals MNO and MNO equals PQR then ABC does not equal PQR by the transitive property.
