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
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.

The shapes of some typical orbitals are discussed below. Shape of s-Orbitals. In order to draw the shape of s-orbital, we first need to recall the radial part of the same and then we will have to superimpose the angular part. For instance, the radial part of 1s orbital is. 1 3/2 (443) − / 0 1,0 = 2 ( ) 0.
An s orbital is spherically symmetric around the nucleus of the atom, like a hollow ball made of rather fluffy material with the nucleus at its centre. As the energy levels increase, the electrons are located further from the nucleus, so the orbitals get bigger. The order of size is 1s < 2s < 3s < …, as shown below.
In this worksheet, students will learn how to properly fill in the arrows of electron orbital diagrams, following Hund's Rule, the Pauli Exclusion Principle, and the Aufbau Principle. This worksheet only includes s, p, and d-block elements.
