Chemistry Structure of Atom MHT CET 2023

Which of the following statement is NOT true about atomic model?

(A)An electron in hydrogen atom can move around the nucleus in one of the many possible orbits of fixed radius and energy
(B)The energy of an electron in the orbit does not change with time
(C)An electron can move only in those orbits for which angular momentum is integral multiple of
(D)This model can explain the ability of atoms of form molecules by chemical bonds.Correct

Answer: (D)

Solution

The statements describe Bohr's model. (a) Electrons revolve in certain permitted orbits (stationary states) of fixed radius and energy: true. (b) While in a stationary orbit the electron does not radiate, so its energy does not change with time: true. (c) Quantisation of
