Consider these two cases.

Case 1: An electron jumps from energy level 3 to energy level 7 in an atom.

Case 2: An electron jumps from energy level 3 to energy level 9 in an atom.

For case 1, what happens when an electron jumps from energy level 3 to energy level 7 in an atom?

A neutron is absorbed by the atom.

A photon is emitted by the atom.

A photon is absorbed by the atom.

A neutron is emitted by the atom.
Assuming that both cases describe Hydrogen‑like atoms with one electron, for which case is more energy emitted or absorbed?

More energy is emitted or absorbed for case 1.

The energy is the same for both cases.

More energy is emitted or absorbed for case 2.

It is impossible to tell.

Answer:

A photon is absorbed by the atom.

Explanation:

In case 2 where an electron jumps from energy level 3 to energy level 9, a photon is absorbed by the atom.

Photon is the basic unit of energy used to describe electromagnetic radiation.

  • When an electron moves from a lower energy level to a higher one, it absorbs energy.
  • This energy is in form of photon.
  • Level  is a lower energy level compared to 9.

II. A photon is absorbed by the atom.

It is the same scenario as case 2

III. More energy is emitted or absorbed for case 2.

More energy is emitted or absorbed for case 2 because the transition involves movement from a level to a greater level than that of case 1.
