NEET Chemistry (general) MCQ Question
Type: MCQ-conceptual-Hard-Class 12
Which of the following statements about the p-block elements is correct?
A
Xenon forms stable compounds with both fluorine and oxygen under normal conditions.
B
Phosphorus is present in living cells only as phosphoproteins.
C
The atomic size of group 15 elements increases down the group.
D
All noble gases readily form compounds with other elements due to their complete octet.
Correct Answer
Option C
Detailed Explanation
In the p-block elements, particularly group 15, the atomic size does indeed increase down the group as the number of electron shells increases. Xenon does form compounds with fluorine and oxygen, but only under specific conditions, and not all noble gases readily form compounds due to their full valence shell.
