Consider these two cases. Case 1: An electron jumps from energy level 5 to energy level 2 in an atom. Case 2: An electron jumps from energy level 5 to energy level 1 in an atom. For case 1, what happens when an electron jumps from energy level 5 to energy level 2 in an atom? A photon is emitted by the atom. A photon is absorbed by the atom. A proton is absorbed by the atom. A proton 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. It is impossible to tell. The energy is the same for both cases. More energy is emitted or absorbed for case 2.

Answer:

1. A photon is emitted by the atom.

2. More energy is emitted or absorbed for case 2

Explanation:

The Bohr's model of the atom was based on quantum mechanics idea. He suggested that electrons move in specific spherical orbits round the nucleus.

The claims of his model emphasized on the premise that electrons only move in permissible orbits or energy levels round the nucleus.

The ground state is the lowest energy state available where n= 1.

The excited state is energy levels of n = 2,3,4 .....

Problem 1

For an electron to return to the ground state from a higher energy level, i.e from 5 to 2 in case 1, energy is emitted in form of photons.

Problem 2

More energy is emitted or absorbed when an electron moves from a higher energy level to a more lower one or jumps from a lower energy level to a more higher one.
