Radius of first bohr's orbit of hydrogen...

Radius of first bohr's orbit of hydrogen atom is 0.53 A then the radius of `3^(rd)` bohr orbit is :-

A

2.12 Å

B

8.48 Å

C

4.24 Å

D

1.06 Å

Text Solution

Verified by Experts

The correct Answer is:
B
`r_n prop n^2`
`therefore r_4 = 4^2r_1 = 16r_1 = 16xx0.53=8.48 Å`
