Question

The molecules of phosphorus and sulphur are ______atomic and _______atomic

Answer 1

Answer : The molecules of phosphorus and sulfur are tetra-atomic and poly-atomic.

Explanation :

The element phosphorous with symbol (P) which belongs to the nitrogen family that is, group 15 in the periodic table.

The atomic number of phosphorous is, 15

Atomocity : It is defined as the number of atoms present in the molecule of an element.

The atomicity of phosphorous is, 4. So, the molecules of phosphorus is tetra-atomic.

The atomic size of phosphorus is more so it can form only single bond with the other phosphorus atoms. Hence, it exists as tetra atomic molecule.

The element sulfur with symbol (S) which belongs to the oxygen family that is, group 16 in the periodic table.

The atomic number of phosphorous is, 16

The atomicity of sulfur is, 8. So, the molecules of sulfur is poly-atomic. That means sulfur exists in many allotropic forms.

Hence, the molecules of phosphorus and sulfur are tetra-atomic and poly-atomic.
