TWO(2)
Carbonate is an ANION of the formula ' CO3^(2-) '.
It does NOT exists in the 'free' state, but in combined form , as Calcium Carbonate, or Sodium Carbonate etc.,
The carbonate anion contains two elements viz., Carbon(C) and Oxygen(O) .
They are arranged as ; -
1 atom of carbon
3 atoms of oxygen
With an ionic charge of ' -2 ' .
In 5A
Carbonate is CO32- . It consists of carbon and Oxygen

calcium carbonate
Calcium carbonate is made of the elements calcium, carbon, and oxygen.
Sodium carbonate contains the elements sodium, carbon, and oxygen. Its chemical formula is Na2CO3.
Calcium, Carbon, Oxygen
Calcium carbonate contains three elements. viz. Calcium, Carbon , and Oxygen. The chemical formula is ' CaCO3 '. This tells us that a molecule of calcium carbonate conrains ;- 1 x Calcium(Ca) 1 x Carbon(C) 3 x Oxygen(O3) Thereby one molecule of calcium carbonate contains 3 elements and 1 + 1 + 3 = 5 atoms.
Calcium carbonate is the compound made from the elements oxygen, calcium, and carbon. It is commonly found in rocks, shells, and pearls.
Lead carbonate is PbCO3. there are three elements, lead, Pb; carbon , C; oxygen, O.
Calcium carbonate contains 3 elements, calcium, carbon, and oxygen. The formula is CaCO3.
The number of elements in calcium carbonate is three(3) . viz. 1 x calcium(Ca) 1 x carbon(C) 3 x oxygen(O3) Its chemical formula is CaCO3. Thereby it contains three(3) elements and 1+1+3 = 5 atoms.
