Question

The simple Bohr model cannot be directly applied to calculate the energy levels of an atom with many electrons. This is because [NCERT Exemplar]
(a) of the electrons not being subject to a central force.
(b) of the electrons colliding with each other.
(c) of screening effects.
(d) the force between the nucleus and an electron will no longer be given by Coulomb’s law.

Answer 1

Answer:

(c) of screening effect

becoz bohr's model is highly specific for interaction of a electron and nuclie of atom but when we talk about screening effect then interaction of electron with electron also comes in play and hence bohr's model gets failed
