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 s orbital is located in the first energy shell (energy shell 1). The electron configuration for a fluorine atom is: F 1s2 2s2 2p5. • An atom of fluorine has a total of 9 electrons, and so all of the superscripts in an electron configuration should add up to 9 (2+2+5 = 9).
Shape of Atomic Orbitals (s, p & d) The wave mechanical model of atom says that there is a non-zero probability of finding the electron almost everywhere in space excepting the angular and radial nodes.

Draw the orbital diagrams for the following IONS. This will be the same orbital diagrams as a neutral atom except you've added or subtracted some arrows to represent the electrons that were added or subtracted. See Na for an example. 13.
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.
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.
