Orbital Energies

[lwon Dis2I]

Can someone break down the symbols and explain to me how this equation is derived?

This concept relates to the calculation of electrostatic potential, which i don't think we have to know. We have to be able to relate electrostatic potential energy to ionization energy, but the actual calculation of either is not relevant to the course.

However, if you are still curious about the topic, I am aware of a general trend. Attractions between particles result in a decrease in electrostatic potential, while attractions decrease it.

My question has more to do with orbitals as a concept, but on a recent lecture Professor Lavelle states that "An orbital is a math function with three quantum numbers: n,l,m"
I was a bit confused because I thought orbitals were work functions, not math functions...are they both the same thing, or am I getting it mixed up with a different concept?

As far as I know, orbitals are math functions which represent the likelihood of an electron being at any given point at any given time. They are math functions because they are three dimensional sine waves.

Orbitals are math functions. Work function was from the photoelectric effect section and refers to the minimum energy needed to remove an electron.

Okay thank you, :)
