how many electrons can n=4 l=1 have?
ml can be +l to -l in increments of 1 including zero. So
-1, 0, +1 and each ml can have two electrons in with ms being +1/2 or -1/2. That looks like 6 to me. There's an easier way to do it. if l = 1 that is a p electron and we all know we can have 6 p electrons.
To find the maximum number of electrons in an orbital with the quantum numbers n=4 and l=1, we need to use the formula:
Maximum number of electrons = 2(2l + 1)
Here, the quantum number l represents the azimuthal quantum number, which determines the shape of the orbital. Since l=1, it corresponds to a p orbital.
Plugging in the values, we get:
Maximum number of electrons = 2(2 × 1 + 1)
= 2(2 + 1)
= 2(3)
= 6
Therefore, in an orbital with n=4 and l=1, you can have a maximum of 6 electrons.
