Okay, so this problem, we basically have to make a list of all four quantum numbers for a neon atom.
00:13
And first of all, let's remember that the neon atom has an atomic number z equals 10.
00:25
Therefore we have 10 electrons in the ground state.
00:28
So to make this list of all four quantum numbers, the first step, let's put here, the first step is to make an electron configuration for this atom.
00:44
So electron configuration.
00:55
Okay, so since we have atomic number z -10, the electron configuration for the neon configuration for the neon, is going to be 1 as 2, 2 as 2, and the final 6, 2 p6.
01:18
So this is the electron configuration for neo.
01:24
Remember that in the electron configuration, the numbers in front of the letters, 1 and 2, represents the quantum number n, which represents the energy, it is related to the energy of the electron.
01:47
Okay, so let's begin.
01:49
And here we can see what we have 2, 2 and 6, we have 10 electrons.
01:58
So from this configuration, we can see that the 1 -s, which is the first one, the 1s state has two electrons.
02:15
So we have two electrons because of this index here.
02:20
Therefore we have the quantum number n is going to be one for both of these electrons.
02:32
The quantum number l is going to be zero...
