In a hydrogen-like species, the net force acting on a revolving electron in an orbit as given by the Bohr model is proportional to [ n → principal quantum number, Z → atomic number]

Question

In a hydrogen-like species, the net force acting on a revolving electron in an orbit as given by the Bohr model is proportional to [ n → principal quantum number, Z → atomic number], Z 3 n 4, n 3 Z 2, Z 2 n 3, n 4 Z 3

MARKS App · Accepted Answer

The net force on a revolving electron is F = m v 2 r F ∝ v n 2 r n The velocity of the electron in the n th shell v n ∝ Z n and the radius of the n th shell r n ∝ n 2 Z ⇒ F ∝ Z 3 n 4
