The excited state
1. ___________ is when an electron occupies an
unstable higher energy orbital.
2. __________ is the lowest energy state of an
atom in which all electrons are in the lowest possible energy
orbital.
An electron in a hydrogen atom is excited from the n = 1 ground state to the n = 4 excited state. Classify the statements about this absorption and emission process as true or false. True On average, the electron is closer to the nucleus in the n = 4 state than in the n = 1 state. The wavelength of light absorbed when the electron is excited from the ground state to n = 4 is the same as the wavelength of...
excited state vs the number in the ground state for the
temperatures shown below. Remember that g values are simply the
number of states present in each orbital. g values for the 3p and
3s orbitals are shown below. The average wavelength of light
required to excite an atom from 3s to 3p for Na+ and
Mg+ is 5.89 x 102 nm and 2.80 x
102 nm respectively.

List the quantum numbers for the electrons in the ground state of a neon atom. What are the quantum numbers for the next state to be filled in this scheme? If a single electron were excited by the minimum amount of energy possible, what would then be the configuration of the atom?
Consider a de-excitation of Hydrogen from an excited state n = 3
to the ground state n = 1. The transition to a lower energy state
will cause the atom to emit a photon. Due to momentum conservation,
the atom will have a small recoil velocity. Determine an expression
of the recoil velocity of the hydrogen atom, and compute its
numerical value. Do not leave ΔE or the photon frequency f in your
answer! Note that the atom is non-relativistic.
One excited state of the sodium atom lies at 25 739.86 cm1 above
the ground state, another lies at 50 266.88 cm-1 .
Suppose they are connected by a perturbation equivalent in energy
to (a) 100 cm-1 , (b) 1000 cm-1 , (c) 5000
cm-1 . Calculate the energies and composition of the
states of the perturbed system.
A hydrogen electron, initially in its second excited state
(n=3), jumps down to the ground state n=1. The energy of n=1 state
is -13.6 eV.
A) What is the energy of the photon emitted from this jumping
down process? ( I got 12.08889eV)
B) Is this emitted photon energetic enough to create
photoelectrons from Ni( Ni working function is 5 eV)?
C) If this emitted photon (from the jump down from n=3 to n=1)
is reabsorbed by a hydrogen electron...

In the harmonic oscillator problem, the normalized wave
functions for the ground and first excited states are ψ0
and ψ1. Using these functions, at some point t, a wave
function u = Aψ0 + Bψ1 is constructed, where
A and B are real numbers.
(a) Show that the average value of x in the u state is generally
non-zero.
(b) What condition A and B must satisfy if we want the function
u to be normalized?
(c) For which values...
