How should we depict an atom? Like a solar system with electrons orbiting the nucleus on hula hoop orbits? That idea is so last century! Dr. Stephen Bosi takes us into the quantum world, where an electron's position and velocity aren't well defined - all we can calculate are the probabilities e.g. of finding an electron at different points in space. When we do that, we find electrons do not necessarily occupy circles or spheres in space. Rather their probability densities make all sorts of interesting shapes from the dumbbell to the peanut with the doughnut around it. From Veritasium

Electron Configurations in Atomic Energy Levels [10:35]
This lesson will explain what the electrons are doing inside the atom. Tune in to find out how we specify where they are located and how this location description will help us predict an element's properties.
Four Quantum Numbers: Principal, Angular Momentum, Magnetic & Spin [10:00]
Each atom inside of an electron has its own 'address' that consists of four quantum numbers that communicate a great deal of information about that electron. In this lesson we will be defining each quantum number and explaining how to write a set of quantum numbers for a specific electron.
