Bohr Model | MCQs

Explanation

Bohr's quantum condition states that the angular momentum of an electron in a circular orbit is quantized:

mvr = nh / 2π

where m is the mass of the electron,

v is the velocity,

r is the radius of the orbit,

n is the principal quantum number,

and h is Planck's constant.

Explanation

In Bohr's model, electrons occupy specific energy levels around the nucleus.

When an electron moves from a lower energy level to a higher energy level, it absorbs energy

Conversely, when an electron moves from a higher energy level to a lower energy level, it emits energy.

This energy is emitted as a photon of light with a specific wavelength, corresponding to a specific frequency.
