When we discussed the building up principle, the notes say to "add Z electrons with no more than two electrons per orbital." Does Z refer to the atomic number? I just wanted to make sure that the notation is correct.

Z refers to the atomic number since there must be the same amount of electrons as the number of protons in a neutral element.

Yes, Z refers to atomic number. That's why the textbook sometimes says that the nucleus of an atom of x element has +Ze charge because the atomic number is also the number of protons in the nucleus.

Yeah, Z is the atomic number in this case

For the most part, Z symbolizes the atomic number (or it is also correct referring to it as the number of protons) of an element.

Z is the atomic number for an element, and thus, it is also the number of protons!
