The valency of Carbide is -4. Yet for some unknown/unexplained reasons Calcium Carbide is CaC2 and not Ca2C.
CaO + 3C >> CaC2 + COThis reaction can not be produced at a normal temperature achieved by combustion, but in an electric arc furnace. I can find out no more than that.Added:because the 'valency' of carbide is NOT uniqely -4: Actually in metal salts it's ion is (C2)2- , so with Ca2+ it forms CaC2The structural formule is not C-Ca-C but -Ca-(C=C)- formed in a chain with a triple bond between the Carbon atoms: ..... -Ca-C---C-Ca-C---C-Ca-..... etc.Even in ethyn H2C2 it is considered to have a -2 valency, though this is not a ionic (metal) salt.
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.
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 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 of lithium is 1. It has one valence electron in its outer shell.
Its valency is 0.
the valency is 4
magnesium has a valency of 2
the valency for nitrite is 5
The valency of silver is typically +1. However, silver can also exhibit a valency of +2 in certain compounds.
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 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 common name of silicon carbide is carborundum.
Carbon has a valency of 4, while sulfur has a valency of 6.
