One.
CaCO3 is chalk and it contains one atom calcium.
In a molecule of calcium (Ca), there are no atoms of oxygen. Calcium itself does not contain any oxygen atoms in its molecular formula.
The formula unit of calcium carbonate is CaCO3. Therefore, it has 3 oxygen atoms.
In one molecule of CaF2, there is one calcium atom and two fluorine atoms.
The chemical formula for calcium hypochlorite is Ca(ClO)2. This means that each molecule contains one calcium atom (Ca), two chlorine atoms (Cl), and two oxygen atoms (O), totaling five atoms in one molecule of calcium hypochlorite.
There is 1 atom of calcium in CaCl2. Each molecule of CaCl2 contains 1 calcium atom, 2 chlorine atoms, and a total of 3 atoms.
There are three atoms of oxygen per calcium carbonate molecule. name: chalk IUPAC name: calcium carbonate compound formula: CCaO3 formula: CaCO3 (This information was obtained from http://www.wolframalpha.com)
