Question

Choose the correct statement(s) that are proposed by Neils Bohr, regarding the model of an atom.

• A. Electrons absorb energy when they move to higher energy orbits.
• B. Electrons emit energy when they move to lower energy orbits.
• C. Electrons absorb energy when they move to lower energy orbits.
• D. Electrons emit energy when they move to higher energy orbits.

Answer 1

Answer: (A), (B)

The correct options are
A

Electrons absorb energy when they move to higher energy orbits.

B

Electrons emit energy when they move to lower energy orbits.

Bohr's Model of the atom included the ideas that:

Electrons revolve around the nucleus in fixed paths called shells/orbits and electrons in each shell have a definite energy.

The energy of the shell increases as the distance from the nucleus increases so, electrons emit energy when they move to lower energy orbits and electrons absorb energy in order to move to a higher energy orbit.
