-3 to metals and hydrogen (phophide)
+3 in oxo-compounds (phosphite)
+5 in oxo-compounds (phosphate)
The valency for plumbic is +4. This means that plumbic compounds typically have a charge of +4.
The valency of bromide ion (Br-) is -1.
PO4^-3 is an ion.So its valency is -3
Group number 1 = Valency 1+group number 2 = valency 2+group number 3 = valency 3+group number 4 = valency 4+ and 4- (some cases) group number 5 = valency 3-group number 6 = valency 2-group number 7 = valency 1-group number 8 = valency 0For the transition elements they will either state Copper (III) Sulphate or it will be like Cu2(SO4)3You can find the valency by the base of sulphate and you know its positive because metals are always positive and are written in the left.Source: I am a GCE O Level Sciences Student (O2)
Halogens have a valency of -1.
The valency of lithium is 1. It has one valence electron in its outer shell.
Its valency is 0.
the valency is 4
Phosphorus is a non metal which is located in group 15. It has two valency numbers, namely 3 and 5. The hydride of phosphorous is phosphene, which is an acidic gas.
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.
The valency of sulfur is 2-. The valency of sulfur is 2-. The valency of sulfur (S) is +2
The valency of potassium dichromate is +6. This is because potassium has a valency of +1, and each chromium atom in the dichromate ion has a valency of +6.
The valency for sulphuric acid is H2SO4
Carbon has a valency of 4, while sulfur has a valency of 6.
