Question

Identify the following as molecule of an element (ME) or molecule of a compound (MC). Also, arrange the molecules in the ascending order of their atomicity.​

A. Phosphorus ($P_4$)
B. Sulphur dioxide ($S{O}_2$)
C. Bromine ($B{r}_2$)

Arranging the molecules in the ascending order of their atomicity:

< <

Answer 1

A. Phosphorus molecule is a molecule of element (ME).
B. Sulphur dioxide molecule is a molecule of compound (MC).
C. Bromine molecule is a molecule of element (ME).

Arranging the molecules in the ascending order of their atomicity:

Bromine (Atomicity: 2) < Sulphur dioxide (Atomicity: 3) < Phosphorus (Atomicity: 4)
