If the itom` _(100) Fm^(257)` follows the Bohr model the radius of `_(100)Fm^(257)` is a time the Bohr radius , then find `n` .

A

`100`

B

`200`

C

`4`

D

`1//4`

Text Solution

Verified by Experts

The correct Answer is:
D
KEY CONCEPT : for an atom folloeing Bohr's model , the radius is given by
`r_(m) = (r_(0) m^(2))/(Z) ` where `r_(0) = `bohr's radius and `m = ` orbit number
for Fm , `m = 5` (fifth orbit in which the outenmost
