Question

define atomicity find out the atomicity of the following P4 h10 and C2 h2​

Answer 1

no. of atoms in a molecule is called its atomicity.

atomicity of P4H10 is 14

and of C2H2 is 4

Answer 2

The atomicity of P4H10 is 14 while that of C2H2 is 4.

• The atomicity of a molecule is defined as the number of atoms present in one molecule.
• One molecule of P4H10 contains four phosphorus atoms and ten hydrogen atoms , hence the atomicity of P4H10 is equal to (4+10) = 14.
• One molecule of C2H2 contains two carbon atom and two hydrogen atoms , hence the atomicity of ethylene is equal to (2+2) = 4.
