Ml quantum numbers

[Katryn Heine 3A]

The function of the Ml quantum number really confuses me. Could someone explain what it tells you and how to know? Thank you!

Hi. The ml quantum number shows the orientation of an orbital. It can be referred to as orbitals. The ml value of an electron can be a number from -l to +l. For example, if l=1, the ml values can be -1, 0 and +1.

Furthermore, to add to the discussion, the magnetic quantum number categorizes orbitals inside a subshell such as the px, py, and pz orbitals, which may correspond to a magnetic quantum number of -1, 0, and +1.

To my understanding, it basically tells you how many orbitals are in a subshell. So for example, if the subshell is d, the l number is 2. So ml could be 2, 1, 0, 1, or -2. ml could be 5 values meaning there are 5 orbitals. According to Hund's Rule, 2 electrons can occupy each orbital with opposite spin.

Hi,
The Ml quantum numbers are there to tell you the orientation of the angular momentum (l). That is why when l=0 (s-shell) Ml will be 0, when l=1 (p-shell) Ml will be -1,0,1 for each of the sub-shells, and so on.

The ml number is also used when talking about the subshell's orbitals by labeling each one. This is like when we say "p sub x" "p sub y" "p sub z." It also helps for visualizing what it actually looks like (like the diagrams we saw in class), which you don't have to worry about too much. The x, y, and z refer to the axis that it lays on.

mL stands for the magnetic quantum number and specifies the orientation in space of the orbital or the projection of the angular momentum orbital.

[Joshua Lance Yumul 1F]

Hey! So Ml would refer to the magnetic quantum or orbitals of a subshell. This would indicate the orientation of the electron. With the values, it would depend on the orbital angular momentum. so if l=3, your values of ml would be -3,-2,-1,0,1,2,3. The best trick for me is to just base the values off of what the orbital angular momentum (l) is.

To add to the discussion, another important aspect of this quantum number is that all orbitals (various ml for given l) are degenerate and have the same energy as each other. Varying numbers of l have different energies but all ml under a value l have the same energies.

Ml is the magnetic quantum number and it specifies which orbital the electron is in and the orientation. Usually, the range of ml is -l,..0,..,l and l refers to the angular momentum quantum number.
