MCQ
$\ce{IP}$ values of an element $'X\ '$ are $\ce{104kJ, 200kJ, 420kJ, 2825kJ}$ per mole. Identify the group to which the element belongs?
- A$\ce{IA}$
- B$\ce{IIA}$
- ✓$\ce{IIIA}$
- D$\ce{IVA}$
✓
Answer
Correct option: C.
$\ce{IIIA}$
As there is large jump from $3^{rd}$ to $4^{th} \ \ce{IP}$ value, the valency of $'X\ '$ would be $3.$
The group number is equal to the valency.
The group number is equal to the valency.
