Question

What does Bohr’s second postulate state about the electron orbiting around the nucleus?

Options

• Its orbit contains no standing waves.

• Its angular momentum is quantised.

• Its momentum is always zero.

• Its speed is much less than the speed of light.

Answer 1

Bohr’s second postulate assigns only specific values to the angular momentum of the orbiting electron. These values are integral multiples of \[h/(2\pi)\].
