Chemistry Structure of Atom MHT CET 2023

Which of the following statements is NOT true about Bohr 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 to form molecules by chemical bondsCorrect

Answer: (D)

Solution

Bohr's postulates: electrons revolve in certain permitted circular orbits (stationary states) of fixed radius and energy (a, true); while in a stationary orbit the electron's energy remains constant and no radiation is emitted (b, true); and only orbits whose angular momentum is an integral multiple of
