How To write an electron configuration: Determine the total number of electrons to be represented. Use the Aufbau process to fill the orbitals with electrons. The Aufbau process requires that electrons fill the lowest energy orbitals first. In another words, atoms are built from the ground upwards.
we will learn how to use the periodic table to remember the orbital structure, and then write it using the shorthand notation of electron configurations. Some things to remember: • Each orbital can contain 0, 1, or 2 electrons (and no more!). • Electrons always fill up the lowest energy orbital first. The lowest energy orbital is in shell 1
When atoms bond to form molecules, they use molecular orbitals. These are formed through the hybridization of the atomic orbitals that we have already discussed, s, p, and d orbitals. The hybridized molecular orbitals have different shapes and energy levels than the atomic orbitals.
Practice problems on determining the sp3, sp2, sp, sp3d and sp3d2 hybridization of atomic orbitals as well as the geometry of the atom.
The four different types of orbitals (s,p,d, and f) have different shapes, and one orbital can hold a maximum of two electrons. The p, d, and f orbitals have different sublevels, thus can hold more electrons. As stated, the electron configuration of each element is unique to its position on the periodic table.

Orbitals have different shapes and sizes, depending on the energy of the electron. To understand how orbitals work, we must first consider quantum numbers, each describing a certain property.
