Ca + Cl2 --> CaCl2
or
Ca2+ + 2 Cl- --> CaCl2
negatively
negatively
Calcium chlorate has the formula Ca(ClO3)2. Therefore, there are two chlorine atoms in each formula unit.
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.
calcium and chlorine combines to produce CalciumChloride (CaCl2) as chlorine needs 1 electron to complete its octate... and calcium needs to lose 2 electrons to stablized.. therefore 2 atoms of chlorine react with a single atom of calcium to stablized. Atomic numbers are as follow : Calcium 20 Chlorine 17
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 and chlorine atoms
negatively
negatively
calcium atoms, sodium, chlorine, and sulphur atoms
No. If two atoms are the same then they are of the same element. The type of atoms is determioned by the number of protons in the nucleus. A chlorine atom has 17 protons, a calcium atom has 20.
Calcium chlorate has the formula Ca(ClO3)2. Therefore, there are two chlorine atoms in each formula unit.
