f- orbitals?

in lecture, lavelle really only said we needed to be familiar with s, p, and d blocks when writing electron configurations .
but in homework problem 1D.21 part C, the answer was in terms of the f orbital.

do we still only need to know the s, p, and d blocks, or should i familiarize myself with "f" too when writing electron configurations?

It is definitely a useful thing to know, and it's good to practice it so that you are aware of it, even though it may not appear in class or on a test. However, if you ever study radioactivity in chemistry, then knowing how to determine figurations of the f-block may come in handy. For f-block, take the number of the period it appears to be in and subtract 2.

Since this is a chemistry class with a focus on the life sciences, most of the elements we will be dealing with fall into the s, p, and d blocks, which is why Dr. Lavelle said that those are the ones we should be focusing on when studying. They will be the ones that appear most frequently in examples and problems. However, as seen in this problem, it is still useful to acquaint yourself with the f-block, which may also be referenced though not as frequently.

I think its good to know how to do e- configurations for f. The concept it good to know because there could possibly be conceptual questions on e- configurations, but since he said we didn't need to know e- configurations for f orbitals for the exam there probably won't be a directed questions on f orbitals.

Being familiar with the f- orbitals can be helpful in having a more holistic understanding of electron configurations and orbitals, but Dr. Lavelle mentioned that we do not have to worry about them for exams. Just be familiar with the s, p, and d blocks.
