An element has four quantum numbers associated with it. We have
1. principal quantum number (
)
2. azimuthal quantum number (
)
3. magnetic quantum number (
)
4. spin quantum number (
)
To look for each quantum number of Chlorine (Cl), we mus first recall its electronic configuration:
.
1. For, we need to look for its highest energy level or by simply checking the period that the element belongs to. So for this case, it's 
.
2. For, we need to look for the sublevel where the last electron was assigned. The sublevels, p, d, f are assigned to a value of 0, 1, 2, and 3, respectively. Since the last electron was assigned in p, then 
.
3. And for, the number of orbitals present in Cl is 
. The possible magnetic quantum numbers for 
are -1, 0, +1. Since there 5 electrons we count starting at -1. So, we have ![m_{l}=+1[tex].\\4. Lastly, for [tex]m_{s}](https://tex.z-dn.net/?f=m_%7Bl%7D%3D%2B1%5Btex%5D.%5C%5C4.%20%20Lastly%2C%20for%20%5Btex%5Dm_%7Bs%7D)
, we need to determine the spin. Since we have 5 electrons, all the arrows upward are filled in. That means the fifth electron has a spin of +1/2.
