Question 3
Part B:How many values of ml are possible for an
electron with orbital quantum number l = 1?
Express your answer as an integer.
Part C
The quantum state of a particle can be specified by giving a
complete set of quantum numbers (n,l,
ml,ms). How many different
quantum states are possible if the principal quantum number is

The quantum state of a particle can be specified by giving a
complete set of quantum numbers (n,l,
ml,ms). How many different
quantum states are possible if the principal quantum number is
n = 2?
To find the total number of allowed states, first write down the
allowed orbital quantum numbers l, and then write down the
number of allowed values of ml for each orbital quantum
number. Sum these quantities, and then multiply by 2 to account for
the...

One of your classmates (Filomena) traveled to a different
universe and found out that the spin quantum number for the
electron was s = 3/2 instead of 1/2 but all other
properties of the electron were. The Pauli exclusion principle also
holds in this different universe.
Describe qualitatively the outcome of a Stern-Gerlach
experiment on hydrogen atoms in this universe.
