Question
The radius of first orbit of H-atoms is 0.529 Å. The radius of first orbit of D-atoms should be
Options
A.exactly 0.529 Å.
B.slightly less than 0.529 Å.
C.slightly greater than 0.529 Å.
D.1.058 Å.
Solution
Reduced mass effect: $r' = r.\left( 1 + \frac{m_{e}}{m_{n}} \right)$
On increasing the nuclear mass, radius decreases.
