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.
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)
There are 3 atoms present in CaCl2: 1 calcium atom (Ca) and 2 chlorine atoms (Cl).
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.
CaCl2 is a compound that has 3 atoms in it; one calcium (Ca) atom, and two chlorine (Cl) atoms.
3 atoms. One calcium and two chlorine. However, there are only two different atoms: calcium and chlorine.

Number of chlorine atoms in CaCl2?
There are two chlorine atoms in CaCl2.
How many chlorine atoms are there in two calcium chloride formula units?
There are four chlorine atoms in two calcium chloride formula units (CaCl2) because each formula unit contains two chlorine atoms.
Write a correct formula for calcium chloride?
The correct formula for calcium chloride is CaCl2, which signifies that one calcium atom is bonded to two chloride atoms.
How many chlorine atoms are needed to link up with one calcium atom?
One calcium atom typically forms ionic bonds with two chlorine atoms to create calcium chloride (CaCl2).
How many O atoms are present in sodium chlorite?
There are three oxygen (O) atoms present in sodium chlorite (NaClO2).
How many atoms of calcium are 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.
How many total atoms are in the function CaCl2?
Three.
How many atoms are in 3 CaCl2?
3 CaCl2 has 3 calcium atoms and 6 oxygen atoms.
Number of chlorine atoms in CaCl2?
There are two chlorine atoms in CaCl2.
The chemical formula for calcium chloride CaCl2 shows that the compound contains two?
Chlorine atoms, which are present as chloride ions.
What type of bonding is present in cacl2?
Ionic bonding is present in CaCl2. In this type of bonding, electrons are transferred from the calcium atom to the chlorine atoms, creating oppositely charged ions that are held together by electrostatic forces.
How many atoms are in 2CaCl2?
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.
How many atoms each element of CaCl2?
Calcium chloride (CaCl2) consists of one calcium atom (Ca) and two chlorine atoms (Cl) in each molecule.
How many formula units are present in 2.50 moles of CaCl2?
There are 3.01 x 10^24 formula units of CaCl2 in 2.50 moles. This can be calculated using Avogadro's number (6.022 x 10^23) and the formula units present in one mole of CaCl2 (3).
How many ions are present in CaCl2?
CaCl2 consists of 1 calcium ion (Ca2+) and 2 chloride ions (2Cl-), so a total of 3 ions are present in CaCl2.
How many Number of atoms in calcium chloride?
There are 5 atoms in one formula unit of calcium chloride (CaCl2): one calcium (Ca) atom and two chloride (Cl) atoms.
What does the 2 mean in CaCl2(aq)?
The 2 in CaCl2 means that there are two Cl (Chlorine) atoms in each formula unit.
