Atomic Structure Question 486
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} $
