Now, the shell of an atom can be further divided into subshells, also known as sublevels, with each one assigned a variable letter. Alright. So we have our shell numbers 1, 2, 3, and 4. We're gonna say here that our subshells that can be linked to these are if it is 1, then the subshell letter that is possible is s. If n=2, then possible values are s and p. If n=3, then possible values are s, p, d. And if n=4, then the possible variables that exist are s, p, d, and f. So realize as that n value increases, the variable letters involved increase. Here, we're not going to go past the variable of f. So if we did n=5, we'd still be dealing with s, p, d, and f at that point. Okay? So just remember, these are your 4 variable letters that are possible tied to the shell number.

What are the possible values for n and subshell letter for an electron found in the 3rd energy level and d sublevel? Alright. So we're going to say here that if you are a third energy level or 3rd shell number, that means your n = 3. So automatically a is out and c is out. The answer is either b or d. Next, it tells me that I'm dealing with a d sublevel. Well, remember, a sublevel, a subshell, they're the same thing. So it's telling me the variable for the sublevel and therefore the subshell. They'd be the same. So the subshell letter would still be d. That means that my answer has to be option b. So that'd be the correct answer out of all the choices that are given.
Provide all the possible values of l for a 2 energy level.
