Question

group 15 elements
occurance
electronic configration
atomic and ionic radii
ionisation enthalpy ​

Answer 1

Answer:

occurrence : abundant in the air

electronic configuration: nS²nP³

atomic and ionic radii: Increases down the group

ionization enthalpy : decreases down the group

Explanation:

Group 15 elements : Nitrogen, Phosphorous, Arsenic, Antimony, Bismuth, Moscovium

Occurrence: nitrogen is the major constituent of air, it is about 78% of the air by volume. Phosphorous is present is the plants and animals. The rest of the elements are mostly present as sulfides.

electronic configuration: nS²nP³

atomic and ionic radii: Increases down the group, due to the addition of energy levels.

ionization enthalpy ​: down the group, the ionization enthalpy values decreases.

Answer 2

Occurance : Nitrogen is Abundant in atmosphere. Elements like phosphorous, arsenic exists in Earth's crust as compounds. Antimony and Bismuth are metals and are found in Earth's crust in form of ore.

Electronic configuration: ns²np³

Atomic and ionic radii: Increases down the group from Nitrogen to Bismuth as the number of shells increases

Ionization enthalpy : decreases down the group
