For example sodium oxalate has the chemical formula Na2C2O4.
Ammonia is not an element and therefore does not have either a symbol or valency. Instead it has the chemical formula NH3.
I'm betting on hydrogen phosphide (hydrogen which has a valency 1 combines with phosphide which has a valency 3)
The formula for copper(I) nitride is Cu3N. Nitride has a valency of -3
Yes, hydroxide has a valency of 1. So sodium hydroxide - NaOH - is a compound with Na having a valency of 1 and hydroxide having a valency of 1. For calcium hydroxide, in which calcium (Ca) has a valency of two (2), the formula is Ca(OH)2.
I think the formula of aluminate is AlO2 and valency is 1
Its valency is -2 Its chemical formula is Cr2O7
The number of electrons needed to lose or gain is its Valency
Valency of k=1+ valency so4=2- after crisscrossing the valencies, we get- chemical formula- k2so4
The formula Fe3O4 is an empirical formula, and a more nearly structural formula is FeO.Fe2O3, which shows valency 2 in its first part and valency 3 in its second part. Two-thirds of the iron cations have valency 3 and the others valency 2, combined in a single crystal structure.
The formula for a sulphate ion is SO42- so the valency of a sulphate ion is -2.
Zincate ion has the valency of 2 as the formula is [Zn(OH)4]2- or simply ZnO22-.
For example sodium oxalate has the chemical formula Na2C2O4.
