Which of the following has maximum ionisation energy?

Question

Which of the following has maximum ionisation energy? (A) Caesium (B) Fluorine (C) Xenon (D) Nitrogen

Tardigrade Admin · Accepted Answer

Ionisation energy is the amount of energy required to take out most loosely bonded electron from isolated gaseous atom. Its value increases in a period and decreases in a group.

∴

Among

C s, F, X e

and

N

, ionisation energy of

F

is highest.

Ionisation energy is the amount of energy required to take out most loosely bonded electron from isolated gaseous atom. Its value increases in a period and decreases in a group. ∴ Among Cs,F,Xe and N, ionisation energy of F is highest.

Ionisation energy is the amount of energy required to take out most loosely bonded electron from isolated gaseous atom. Its value increases in a period and decreases in a group.
$∴$ Among $C s, F, X e$ and $N$ , ionisation energy of $F$ is highest.
