Question

Which of the following statement is correct regarding Bohr's atomic model?

• A. Energy of an electron is constant in a particular orbit.
• B. Electrons move to lower energy orbits by absorbing energy.
• C. Electrons move to higher energy orbits by emitting energy.
• D. Electrons revolve around the nucleus in elliptical orbits.

Answer 1

The correct option is A Energy of an electron is constant in a particular orbit.

Bohr's model of the atom proposed that:

$\bullet$ Electrons revolve around the nucleus in concentric circular orbits. The energy of an electron is constant in a particular orbit.

$\bullet$ Electrons emit energy when they move to lower energy orbits from higher energy orbits.

$\bullet$ When an electron jumps from an inner (lower energy) orbit to an outer (higher energy) orbit, it absorbs energy.
