Re: Quantum Numbers
ml gives the orientation of the orbital, and therefore distinguishes between the different orbitals in a s- p- d- or f- subshell. Since the actual orientation of the orbitals is arbitrary, you don't have to know the exact value of ml for a given orbital. Instead, you should know for that any given subshell, there is a range of values ml can be. The range consists of l ... -l.
For example:
In a d-subshell, l=2, ml can be 2,-1,0,1, or 2
For a s-subshell, l=0, ml=0 only
For example:
In a d-subshell, l=2, ml can be 2,-1,0,1, or 2
For a s-subshell, l=0, ml=0 only

Re: Quantum Numbers
Hello! ml labels the different orbitals of a subshell, giving the orientation of the angular momentum. You can find ml by following ml = l, (l-1) ... , -l ; for example n=2 has the sub-electrons -1, 0, 1 because l=1. Hope this helps!

Re: Quantum Numbers
We can find the third quantum number ml by using the angular momentum number. The third quantum number, or the magnetic quantum number, has a range from -l to l. Thus, if the angular momentum number is 2, the possible values for the magnetic quantum number are -2, -1, 0, 1, 2!

Re: Quantum Numbers
Each energy level subshell: s, p, d, and f, have different amounts of orbitals. S has 1 orbital, P has 3 orbitals, D has 5 orbitals, and f has 7 orbitals. The 3rd quantum number ml is used to narrow down which of these orbitals an electron is found in. The ml quantum number ranges from positive l to negative l. For example, the p subshell has an l quantum number value of 1, so its ml values could be -1, 0, or 1 to represent its 3 orbitals. The same goes for all of the other sub shells.

Re: Quantum Numbers
To find the 3rd quantum number (ml), it's important to know l first since ml = l, (l-1), -l.
Example: 2p orbital
In the 2p orbital, we know that n=2 and l=1 because it's a p-orbital with an energy level of 2. Since l=1, ml=1,0,-1.
Example: 2p orbital
In the 2p orbital, we know that n=2 and l=1 because it's a p-orbital with an energy level of 2. Since l=1, ml=1,0,-1.

Re: Quantum Numbers
ml is simply which orbital of a subshell an electron is in. The value of ml can be anywhere from -l to l. If l =1, ml can be -1, 0, or 1.

Re: Quantum Numbers
The third quantum number, ml, is found by using the angular momentum quantum number. Quantum number ml has a range of -l to l. If l is equal to 1, ml could be -1, 0, or 1. Hopefully this is helpful!

Re: Quantum Numbers
The allowed values of the magnetic quantum number (ml) range from -l to l. For instance, if the angular momentum quantum number is 2 (l=2), then ml can be -2,-1,0,1, or 2.

Re: Quantum Numbers
Hi! Possible values for the third quantum number ml are based on the second quantum number l: -l...+l. For example, if the value for l was 1, the possible ml values would be -1, 0, +1. Hope this helps!
Re: Quantum Numbers
Usually, the range of ml is -l,..0,..,l and l refers to the angular momentum quantum number. For example for 2p, n=2, l=1, therefore, ml=-1,0,1. Ml is the magnetic quantum number and it specifies which orbital the electron is in and the orientation.

Re: Quantum Numbers
How I always think of it is the third quantum number, ml, is based on the second quantum number, l, therefore if l is 3, then ml could be -3, -2, -1, 0, 1, 2, 3.
