The mass number of an iodine nucleus and a polonium nucleus is and respectively. The ratio of radius of iodine nucleus to that of polonium nucleus is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
Recall the relation between atomic mass number and radius of the nucleus, R=R0A13, given, Ai=125 & Ap=216, the masses of iodin and polonium respectively, now put these values, RiRp=AiAp13=12521613⇒RiRp=56
