-1 valency
The valency of sulfur is 2-. The valency of sulfur is 2-. The valency of sulfur (S) is +2
The name of the compound SnBr is tin (II) bromide.
Lithium Bromine
The valency of sodium in sodium sulfate is +1, while the valency of sulfate is -2. Therefore, the valency of sodium sulfate as a whole is +2.
S = +6 valency O = -2 valency
The valency of bromide ion (Br-) is -1.
The formula for bromide ion is Br-. The valency of bromide ion is -1, as it has gained one electron to achieve a full outer shell of electrons.
Bromine forms anion. It gets a charge of -1 to form bromide ion.
in the valence shell of bromide 7 electrons are present. So the valency of bromide is 1
You have to use configuration of electrons (spdf). In this case it will only go up to d. if we use the short hand configuration then bromine is 3d10 4s2 4p5. remember d goes before everything.
The valency of lithium is 1. It has one valence electron in its outer shell.
the valency is 4
Its valency is 0.
the valency for nitrite is 5
magnesium has a valency of 2
The valency of ferricyanide is -3. It contains one iron (III) cation with a valency of +3 and one cyanide anion with a valency of -1.
The valency of silver is typically +1. However, silver can also exhibit a valency of +2 in certain compounds.
