Answer 1

Part A

the first ionization energy of nitrogen:

answer: D. N(g)→N+(g)+e−

Ionisation energy can be defined as the amount of energy required to remove an electron from the neutral gaseous atom.

If we apply this energy, the gaseous atom attains positive charge and loses an electron.

Part B

the second ionization energy of nitrogen:

answer: C. N+(g)→N2+(g)+e−

Second ionisation energy is applied on a gaseous cation.

Due to this the cation attains +2 charge along with the evolution of an electron.

Part C

the electron affinity of nitrogen:

answer: A. N(g)+e−→N−(g)

Electron affinity: It is defined as the amount of energy released when an electron is gained by a neutral gaseous atom.
