when n=5 and l=4

Postby Funmi Baruwa » Wed Oct 28, 2020 10:08 am

When the quantum number n is equal to five, l is then equal to 4. So in this case, what orbital does the 4th shell fall under then?

I don't believe that because n=5 that l has to automatically equal 4. l is based on the orbitals while n is the energy level. For example, if the configuration is [Kr] 5s^2 n=5 while l=0 as Strontium is in the s-orbital. Hope this helps!

n is the principle quantum number and represents the energy level an electron is located. l is the angular momentum of e and describes the shape of the orbital. n and l are not dependent on each other; you can have 4s, 4p, and 4d orbitals, where n=4 but l can be 1, 2, and 3 respectively.

General rule is that l is n-1. So the s orbital would be 0, p would be 1, and so on. When asked those types of problems on sapling, that is the easiest way to find the answer.

Although n=5 and the general rule is l=n-1, I don't think l automatically equals to 4. l can equal to 1,2,3 or 4 depending on the situation.

When the quantum number n=5, l can theoretically equal 4 but is not necessarily (or realistically 4). When n=5, l can be 0,1,2,3,4 since the values of l range from 0 to n-1. l=4 would also result in subshell g but as far as I know, no ground state elements have electrons in the g subshell.

n=5 and l=n-1, so l=4, it doesn't necessarily mean l=4 because l can also equal 3,2,1,0

If n=5, then l can theoretically equal 0,1,2,...,n-1

for the last part of your question..."shell" refers to the principle quantum number, n, and "subshell" refers to the angular momentum, or the subshell/orbitals or s/p/d/f. So, the fourth shell would be when n=4, and the orbital/subshell can be l=0,1,2,3 for the "4th shell"

When n=5, l can has the possible values of 0,1,2,3,or 4 as in S,P,D,F, etc. orbitals. The formula to finding l is 0,1,2,...(n-1)

For the purposes of this class, I don't think we have to worry about the subshell when l=4. Just remember l relates to either s, p, d, or f which correspond to 0, 1,2, and 3 accordingly. Conceptually yes, when n=5, l is equal to everything up to n-1 but I don't think we can identify the subshell when l is greater than 3

L would not necessary equal 4, that is just the highest number l can be in this case. This is due to the different types of shells, which have different l levels.

If n is equal to 5, l can equal 0,1,2,3... (n-1), it does not necessarily have to be 4. When l is equal to 0=s, 1=p, 2=d, and 3=f.

When n=5 the general rule is that l=n-1 but that isn't always the case as l could potentially be 0,1,2,etc. For Sapling questions though, unless they give you a specific element, I would use the general rule for determination and l=4 corresponds to the letter g.

oh okay thank you for the bit about sampling too.

The professor said that we don't have to apply quantum numbers to "n" values greater than four for this class. Someone else should verify that, though.

I don't think we need to know the answer to this question since we usually are given values of l up to 3. l=0 corresponds to the s subshell, and l=1 corresponds to the p subshell. l=2 corresponds to the d subshell, and l=3 corresponds to the f subshell. Since there aren't any other subshells that we need to know besides s,p,d, and f, we won't need to know what orbitals correspond to l=4.
