What is the magnetic quantum number of chlorine?

Answer 1

Oh, dude, the magnetic quantum number of chlorine is -1, 0, or 1. It's like this little number that helps describe the orientation of the electron's orbital in a magnetic field. So, yeah, it's kind of a big deal in the quantum world, but like, no need to lose sleep over it.

Answer 2

Answer is at the end, skip to there if you just want the answer.

Chlorine has 17 electrons.

To find the four quantum numbers you first find N.

Chlorine's electron configuration is

1s^2 2s^2 2p^6 3s^2 3p^5

Chlorine's last electrons occupy the 3p subshell. Therefore N = 3

Next you find l (Lower Case L)

Every subshell letter has a numerical value. S=0 P=1 D=2 F=3 Until you reach (N-1)

Remembering the last electron ends in the 3p subshell, we find P=1 so l=1

Next we find the Magnetic Quantum Number which is anywhere from (-l)-0-(+l) in value. Finding this value requires more of an understanding of subshells. S subshells can hold 2 electrons, P subshells can hold 6, and D can hold 10. These occur in pairs of two.

Cl's electron configuration is 1s^2 2s^2 2p^6 3s^2 3p^5

Imagine each shell containing boxes that hold two electrons. Each box has a value.

Since 3p holds 6 electrons, it will have 3 boxes of two. Fill the boxes with one electron each as an up arrow, and then add a second electron as a down arrow from left to right, until you have used all 17 of Chlorine's electrons. If you do that it will look like this.

3p [II] [II] [I ]

The first box's Magnetic Quantum number will be -1 the middle will be 0 and the first will be +1. The last electron we drew was in the middle box, which equals 0.

To find ms or the Spin Magnetic Number you imagine the up arrows as +1/2 and down arrows as -1/2. Because the last electron drawn was a down arrow, it equals -1/2.

Consider all these numbers together and ...

Chlorine is as follows:

N:3 (Because of the 3 in 3p)

l:1 (Because p equals 1)

ml:0 (Because of where the final electron drawn ends)

ms: -1/2 (Because the last electron drawn was a down arrow)

Answer 3

The magnetic quantum number (m) of chlorine is determined by the orientation of its electron within a magnetic field. It can have values ranging from -l to +l, where l is the principal quantum number. For the chlorine atom, the magnetic quantum number can take on values of -1, 0, or +1.
