The are 24 valence electrons in a carbonate ion. http://www.800mainstreet.com/5/0005-006b-lewis.html
Carbonate does not have a valency per se, but if you mean what is the charge on the carbonate ion, then it is -2. Carbonate is (CO3)2-
According to me the valency of carbon is 2
Actually.. the valency of a carbonate ion (not carbon alone) is 2- and the valency on carbon is 4

carbonate symbol: CO3-2
and Valency is the same as the number of charges.
-2
F 1
The chemical symbol for ammonium is NH4, and it has a valency of 1. Remember ammonium is a radical.
The chemical symbol for sodium carbonate is Na2CO3.
Hydrogen carbonate is a compound, not an element, and it therefore has a formula, not a symbol: H2CO3.
-1 valency
A hydrogen carbonate ion has the formula HCO3- so the valency of a hydrogen carbonate ion is -1.
Symbol: Cl-Valency: -1.
2
Na+ valency is one
Ammonia is not an element and therefore does not have either a symbol or valency. Instead it has the chemical formula NH3.
Symbol of nitride is N and its valency is 3
F 1
The symbol of Silver is Argentum or Ag and valency is positive 3
The chemical symbol for ammonium is NH4, and it has a valency of 1. Remember ammonium is a radical.
The symbol equation for Potassium Carbonate is...K2CO3:)
The chemical symbol for sodium carbonate is Na2CO3.
Hydrogen carbonate is a compound, not an element, and it therefore has a formula, not a symbol: H2CO3.
