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 going to say here that our subshells that can be linked to these numbers are: if \( n = 1 \), then the subshell letter that is possible is \( s \). If \( n = 2 \), then the possible values are \( s \) and \( p \). If \( n = 3 \), then the possible values are \( s, p, \) and \( d \). And if \( n = 4 \), then the possible variables that are possible, the possible barriers that exist are \( s, p, d, \) and \( f \). So realize that as the \( n \) value increases, the variable letter involved increases. 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 of an.

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 in the third energy level or the 3rd shell number, that means your n = 3. So automatically option a is out and option c is out. The answer is either option b or option d. Next, it tells me that I'm dealing with a d sublevel. Well, remember, a sublevel and a subshell are 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 were given.
Provide all the possible values of the subshell for a 2 energy level.
