The valency of bromide ion (Br-) is -1.
The bromine ion is referred to as bromide, and it is Br^-
A metal bromide contain the ion Br-; sodium bromide is an example.
An arsenide ion is larger than a bromide ion, but a bromide ion is larger than an arsenic ion. Recall that arsenic can have several oxidation states. It can be a cation or an anion.
Bromine belongs to group-17. When it gains one electron, it forms bromide ion.
The chemical formula of the compound formed between cobalt (III) and the bromide ion it would be CoBr3, if this compound exist !
Bromine forms anion. It gets a charge of -1 to form bromide ion.
-1 valency
the valency of silicate ion is 4-
The formula for a sulphate ion is SO42- so the valency of a sulphate ion is -2.
The bromide ion always has a 1- charge.
The bromide ion has a 1- charge.
Valency = 2 -
in the valence shell of bromide 7 electrons are present. So the valency of bromide is 1
A bromide ion has a charge of -1.
The sulfite ion has a valency of 2.
the valency of silicate ion is 4-
the charge of the bromide ion in AlBr3 is -1
