Question

In Bohr model of the hydrogen atom, let R, V and E represent the radius of the orbit, speed of the electron and the total energy of the electron respectively. Which of the following quantities are proportional to the quantum number n :

TestHub · Accepted Answer

The radius R is proportional to n 2 . R ∝ n 2 The velocity V is proportional to n 1 ​ . V ∝ n 1 ​ The energy E is proportional to n 2 1 ​ . E ∝ n 2 1 ​ Therefore, E V ​ ∝ 1/ n 2 1/ n ​ ∝ n . So, V / E is proportional to n .
