Question

Write the atomicity of (b) CaCl 2

Answer 1

Answer:atomicity means the number of atoms present in an element or a compound.

in cacl2 cl has 2 atoms and ca has 1 atom as its a compound so the atomicity will be 2+1=3atoms

Hence atomicity of cacl2 will be 3

hope it helps you

Explanation:

Answer 2

The atomicity of calcium chloride is 3.

• The atomicity of a molecule is defined as the total number of atoms present in that molecule. For example, the atomicity of HCl is 2 as it has two atoms one H and one chlorine.
• The chemical formula of calcium chloride is $CaCl_2$.
• Thus calcium chloride contains one calcium or Ca and two Chlorine or Cl atoms.
• So, the atomicity of calcium chloride is 1+2=3.
