According to Bohr's theory the radius of the second stationary state of hydrogen atom is
According to Bohr's theory the radius of the second stationary state of hydrogen atom is
Show Hint
The radius increases with the square of the shell number (\(r \propto n^2\)). If you remember the first shell is ~53 pm, the second is \(4 \times 53 \approx 212\) pm, and the third is \(9 \times 53 \approx 477\) pm.
