Concept explainers
(a)
To show:A hydrogen atom in level
(a)
Answer to Problem 50A
The atom will be ionized as energy of the photon (
Explanation of Solution
Given:
Wavelength of photon,
Atomic level,
Formula used:
Energy of an emitted photon
where
The energy of
Calculation:
As per problem
Calculate the energy of the photon
Substitute the values,
Therefore the energy of photon is
Calculate the value of ionization energy of
Thus the ionization energy of the level is
The energy of the photon is greater than the ionization energy of level
Hence, the atom will be ionized.
Conclusion:
The atom will be ionized as energy of the photon is greater than the ionization energy of the level.
(b)
To calculate:The kinetic energy of the electron in joules.
(b)
Answer to Problem 50A
The kinetic energy of the atom is
Explanation of Solution
Given:
As calculated in part (a.)
The energy of the photon,
The ionization energy of
Calculation:
The energy of the photon,
The ionization energy of
The atom absorbs the photon’s energy to get ionized
The kinetic energy of the atom
Conclusion:
The kinetic energy of the atom is
