Question

According to Bohr's theory of hydrogen atom it can be concluded that the radius of stable orbits is proportional to :

• A. $n^2$
• B. $\frac{1}{n}$
• C. n
• D. $\frac{1}{n^2}$

Answer 1

Answer: (A)

$n^2$

The radius of nth orbit is $r_n=0.53\times \frac{n^2}{Z}{A}^o$. Here, Z is atomic number which is constant for atom.Hence, the radius of stable orbits is proportional to $n^2$.
