  • question_answer
    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:

    A) 8 : 1     

    B) 1 : 8

    C) 1 : 1  

    D) 1 : 32

    Correct Answer: D

    Solution :

    [d] \[T\propto \frac{{{n}^{3}}}{{{Z}^{2}}};\,\,\,\,\,\frac{{{T}_{1,2}}}{{{T}_{2,1}}}=\frac{1}{4}\times \frac{1}{8}=\frac{1}{32}\]
