How many atoms are present in CaCl2?

Answer 1

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.

Answer 2

CaCl2 is a compound (not an element) which is built up of three atoms of two different elements:

1x Ca-atom (= element calcium, Ca, number 20 in the Periodic Table)

and

2x Cl-atoms of the element chlorine (Cl, number 17)

Answer 3

The correct formula is CaCl2. Calcium chloride, CaCl2, is an ionic compound and contains three ions per formula unit, one Ca2+ ion and two Cl- ions.

Answer 4

There Would Be 3 atoms in the Element CaCl2

Answer 5

CaCl2 is a compound that has 3 atoms in it; one calcium (Ca) atom, and two chlorine (Cl) atoms.

Answer 6

3 atoms. One calcium and two chlorine. However, there are only two different atoms: calcium and chlorine.

Answer 7

3 in a molecule.

Answer 8

CaCl3 doesn't exist.

Answer 9

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.
