1.5 Electron Configurations Part I

What is an orbital in the context of electron configurations?

• An orbital is a three dimensional description of the most likely location of an electron around an atom.

• An orbital is a flat, two-dimensional path that electrons follow around the nucleus.

• An orbital is the same as an energy level in an atom.

• An orbital is a fixed point where electrons are always found.
