n (principle quantum number) = 4 l (angular momentum quantum number) = 2 ml (magnetic quantum number) = -2, -1, 0, 1, or 2 ms (spin quantum number) = +1/2 or -1/2
The quantum number set of the ground-state electron in helium, but not in hydrogen, is (1s^2) or (n=1, l=0, ml=0, ms=0). It indicates that the electron occupies the 1s orbital, which has a principal quantum number (n) of 1, an orbital angular momentum quantum number (l) of 0, a magnetic quantum number (ml) of 0, and a spin quantum number (ms) of 0.
2s^2 2p^6 Eight, all together.
Assuming you mean the set of quantum number describing the VALENCE electrons of aluminum, they would ben = 3l = 1ml = -1s = +1/2Of course, since Al has only 1 p electron, ml could also have been 0 or +1 and s could have been -1/2

10 electrons.The angular momentum quantum number is l (small L). This quantum number is dependant on the principal quantum number, and has values, 0 1,2 ..(n-1), where each value of n refers to a subshell known to chemists as followsn= 0, s orbital; n=1, p orbital; n= 2, d orbital; n= 3, f orbital.So we are looking at the d orbitals.There are five d orbitals, with magnetic quantum numbers running from -l to +l, that is -2, -1, 0, +1, +2Each of these can hold 2 electrons (with spin quantum numbers -1/2, +1/2)So we have 10 electrons that can have pricipal quantum numbers of 4 and angular monmentum quantum number of 2.
go to the settings.....

Quantum mechanics is a separate branch of physics. It is a general term given to all quantum physics. There are many subbranches, for example Quantum chronodynamics which describes the strong nuclear interaction.
