Question

State the atomicity of the following molecules: (a)Oxygen. (b)argon. (c)Phosphorus (d)sulphur

Answer 1

oxygen atomicity = diatomic
argon atomicity = monoatomic
phosphorus atomicity = tetra atomic
sulphur atomicity = poly -atomic

Answer 2

Answer: Atomicity is the number of atoms present in the molecule of an element.

a) Oxygen exists as $O_2$ and thus 1 molecule of oxygen contains 2 atoms , therefore atomicity is 2.

b) Argon exists as $Ar$ and thus 1 molecule of argon contains 1 atom , therefore atomicity is 1.

c) Phosphorous exists as $P_4$ and thus 1 molecule of phosphorous contains 4 atoms , therefore atomicity is 4.

d) Sulphur exists as $S_8$ and thus 1 molecule of sulphur contains 8 atoms , therefore atomicity is 8.
