A) 100
B) 200
C) 4
D) ¼
Correct Answer: D
Solution :
[d] For an atom following Bohr's model, the radius is given by \[{{r}_{m}}=\frac{{{r}_{0}}{{m}^{2}}}{Z}\] where \[{{r}_{0}}=\] Bohr's radius and m = orbit number. For Fm, m = 5 (Fifth orbit in which file outermost electron is present) \[\therefore \] \[{{r}_{m}}=\frac{{{r}_{0}}{{5}^{2}}}{100}=n{{r}_{0}}\,\,(\text{given})\]\[\Rightarrow \]\[n=\frac{1}{4}\]You need to login to perform this action.
