Atomic Structure Question 418

Question: If in Bohr’s model, for unielectronic atom, time period of revolution is represented as $ {T_{n,z}} $ where n represents shell no. and Z represents atomic number then the value of $ {T_{1,2}}:{T_{2,1}} $ , will be:

Options:

A) 8 : 1

B) 1 : 8

C) 1 : 1

D) 1 : 32

Show Answer

Answer:

Correct Answer: D

Solution:

  • $ T\propto \frac{n^{3}}{Z^{2}};,\frac{{T_{1,2}}}{{T_{2,1}}}=\frac{1}{4}\times \frac{1}{8}=\frac{1}{32} $
