Calcium chloride.
Chlorine atoms, which are present as chloride ions.
There is no correct chemical formula described in your question. When calcium and chlorine combine, they form calcium chloride with a formula of CaCl2.
The chemical formula CaCl2 represents calcium chloride. It is correct as it shows that the compound contains one calcium atom and two chlorine 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 four chlorine atoms in two calcium chloride formula units (CaCl2) because each formula unit contains two chlorine atoms.
Chlorine atoms, which are present as chloride ions.
There is no correct chemical formula described in your question. When calcium and chlorine combine, they form calcium chloride with a formula of CaCl2.
Calcium chlorate has the formula Ca(ClO3)2. Therefore, there are two chlorine atoms in each formula unit.
A chlorine molecule has the formula Cl2, so it contains two chlorine atoms.
The chemical formula CaCl2 represents calcium chloride. It is correct as it shows that the compound contains one calcium atom and two chlorine 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.

CaCl2
The chemical formula of the compound with three chlorine atoms is Cl3, known as trichloride.
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.
Cl2 everyone it is not that hard, 2 x chlorine is Cl2
