Question

(D) In the Bohr model of the hydrogen atom,the potential energy is given by $U_n = -\frac{ke^2}{r_n}$. Since $r_n \propto n^2$,as $n$ increases,$r_n$

Vedclass · Accepted Answer

Potential energy of electron in $n = 2$ orbit is less than that in $n = 1$ orbit.

Vedclass · Answer

(D) In the Bohr model of the hydrogen atom,the potential energy is given by $U_n = -\frac{ke^2}{r_n}$. Since $r_n \propto n^2$,as $n$ increases,$r_n$ increases. Consequently,the magnitude of potential energy decreases,but because it is negative,the value becomes less negative (i.e.,it increases). Therefore,the potential energy in the $n = 2$ orbit is greater than that in the $n = 1$ orbit. Thus,statement $(d)$ is false.

Which of the following statements about the Bohr model of the hydrogen atom is false?
