Question

An electron in a Bohr model hydrogen atom jumps from the 2nd energy level to the 4th level. Is the photon emitted or absorbed by the atom?

Answer 1

An electron moving from the 2nd to the 4th energy level in a hydrogen atom absorbs a photon, based on the principles of the Bohr model.

Step-by-step explanation:

When an electron in a Bohr model hydrogen atom jumps from the 2nd energy level to the 4th level, the process involves the absorption of a photon. According to the Bohr model, electrons reside in discrete energy levels, and a change in energy level requires the transfer of a specific amount of energy. In this case, the electron is moving to a higher energy level, which means that it must absorb energy in the form of a photon. This is contrary to the process of emission, which occurs when an electron drops to a lower energy level, releasing a photon with energy corresponding to the difference of the two levels.

Answer 2

Photon is absorbed by the atom

Step-by-step explanation:

For an electron to jump from lower energy level to higher energy level it needs some energy. This process can only take place when the atom absorbs energy, which can be in the form of photons. When the electron jumps to higher energy levels, it is known as excited state and it is not stable. So the electron will try to come back to lower energy level and in that process it will release energy.
