Element P belongs to first group and fourth period of the periodic table. Element Q succeeds P in the group and element R succeeds Q in the period. |
The correct increasing order of their atomic radii is |
A) Q < R < P
B) P < Q < R
C) P < R < Q
D) Cannot be predicted.
Correct Answer: C
Solution :
P and Q belong to same group and Q succeeds P i.e., Q is bigger in size than P. Now, Q and R belong to same period and R succeeds Q. Therefore, R will be smaller in size than 0 but will be bigger in size than P.You need to login to perform this action.
