What does Bohr's second postulate state regarding the orbits of electrons in an atom?
A
Electrons revolve only in orbits where their angular momentum is an integral multiple of h/2π.
B
Electrons can occupy any orbit without restrictions on their angular momentum.
C
Electrons emit energy continuously while revolving around the nucleus.
D
Electrons can only exist in orbits with no angular momentum.
Correct Answer
Option A
Detailed Explanation
Bohr's second postulate specifies that the electron revolves around the nucleus only in those orbits for which the angular momentum is some integral multiple of h/2π, indicating quantization of angular momentum.
