Given below are two statements :
Statement I : According to Bohr's model of an atom, qualitatively the magnitude of velocity of electron increases with decrease in positive charges on the nucleus as there is no strong hold on the electron by the nucleus.
Statement II : According to Bohr's model of an atom, qualitatively the magnitude of velocity of electron increases with decrease in principle quantum number.

In the light of the above statements, choose the most appropriate answer from the options given below:

Options:

Answer:
A
Solution:

According to Bohr's model, velocity of electron is given by

Vn=2.18×106×Znm/sec

As we see from the given formula velocity is inversely proportional to principle quantum number.

Vn1n;n,Vn

the magnitude of velocity of electron is independent of positive charges on the nucleus.
