2, the subscript following the chemical symbol for chlorine in the formula.
There are two chlorine atoms in CaCl2.

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 a total of 10 atoms in 2CaCl2. This is because each CaCl2 molecule contains 3 atoms: 1 calcium atom and 2 chlorine atoms. Multiplying by 2, there are 6 atoms in 2 CaCl2 molecules, and since there are 2 molecules, the total number of atoms is 10.
There are three atoms in CaCl2 (calcium chloride) - one calcium atom and two chlorine atoms. It might be argued that there are ions inside the molecule instead of atoms. In that case there is one calcium ion and two chlorine ions.
The equation given is not balanced. To determine the number of atoms in the reactants, you need to balance the equation first. Once balanced, you can count the total number of atoms on each side of the equation.
There are 5 atoms in one formula unit of calcium chloride (CaCl2): one calcium (Ca) atom and two chloride (Cl) atoms.
Three.
The 2 in CaCl2 means that there are two Cl (Chlorine) atoms in each formula unit.
3 CaCl2 has 3 calcium atoms and 6 oxygen atoms.
No, the oxidation number of CaCl2 is not 3. In CaCl2, calcium (Ca) has an oxidation state of +2, and each chlorine atom (Cl) has an oxidation state of -1. This combination allows for the compound to have a neutral charge.
