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

Write the ground state electron configuration of the following neutral elements in orbital notation, orbital notation with arrows and in short hand noble gas notation. Beryllium. Orbital notation: 1s22s2. Orbital notation + Arrows: Noble gas notation: [He] 2s2. Nitrogen.
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.
depict the orbital shapes are intended to describe the region encompassing 90−95% probability density. In a typical drawing of orbital, we first plot the radial wave function and the angular part is superimposed. The shapes of some typical orbitals are discussed below. Shape of s-Orbitals
