The radius of the nth stationary orbit of hydrogen atom is proportional to

Explanation

According to Bohr’s rule, the radius of the nth orbit of a hydrogen atom is: According to Bohr's theory, r = $$\frac{n^2h^2}{4\pi^2mZ_o^2}$$ r ∝ n² The radius of the nth orbit of a hydrogen atom is proportional to n². This means the orbit radius increases in proportion to the square of the principal quantum number (n). Therefore, option (c) is true. ## Physical and Chemical Change, Solution
