Orbital Hybridization Written by tutor Michael M. Overview The process by which we determine orbitals is a bit complex and relates to solutions of the Schrodinger equation. Luckily, you won’t deal with this in an introductory chemistry class. Rather, we mostly focus on understanding the concepts of orbitals. Essentially, these orbitals tell us the probability of finding an electron in... read more

Aufbau Principle Written by tutor Alix B. A common homework, quiz, or exam question in general chemistry courses might read, “What is the ground state electron configuration for sodium?” If you are taking a chemistry class, you have probably seen some variation of this question. Perhaps your instructor asked about a different element than sodium, or perhaps you were asked to write an... read more
