Interpretation : When a hydrogen atom absorbs a quantum of energy what happens to be explained?
Concept Introduction : The nature and behavior of matter and energy at the atomic level are essentially explained by quantum theory. To explain the hydrogen atomic emission spectrum, Bohr used quantum theory to consider the energy levels of electrons within atoms.

Answer to Problem 54A
When a hydrogen atom absorbs a quantum of energy, it gets excited to a higher level and then comes to the ground energy level by emitting light in quantum.
Explanation of Solution
The single electron in the hydrogen atom can only have a limited range of energies according to the
The atom is in its ground state when the electron has the lowest energy it can have.
The excitation of the electron occurs when the hydrogen atom absorbs a quantum of energy.
The excited electrons come back to the energy level where light is emitted in the form of a quantum of energy.
