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).
This worksheet provides extra practice for writing electron configurations. The easiest and most reliable technique for writing electron configurations is to use the periodic table as your guide. Details of using the periodic table as a guide for determining electron configurations can be found on the CH301 website. 1.

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. There are four quantum numbers: • n: the principal quantum number zero integer: 1, 2, 3, 4... with the size of the orbital increasing with
A worksheet (and full solution, graphic answer key) that begins reviewing atomic orbitals (s, p, d, f) and progresses to molecular orbitals and geometry. The students are required to draw Lewis Dot Structures and connect to Natta Projections to determine the geometry around central atoms.
