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.
Realised that atoms are divisible and contain very tiny, negatively charged particles called electrons. Discovered that an atom is made up of a nucleus and an extra-nuclear part. The central nucleus is positively charged and the negative electrons revolve around this central nucleus.

An electron shell diagram worksheet is a learning tool that helps students visualize the arrangement of electrons in an atom. It provides a clear representation of how electrons occupy different energy levels or shells, which is essential in understanding the periodic table and chemical bonding.
How electrons are arranged in atoms and ions • Electrons are arranged in electrons shells (energy levels), which themselves have sub diagram below represents the first four main shells of electrons (the exact energies and distance from the nucleus vary and are simplified). Energy 1s 2s 2p
The electron structure of an atom is very important. Scientists use the electronic structure of atoms to predict bonding in molecules, the charge(s) an atom might have, and the physical properties of elements.
In this lesson we will learn (a) how the combination of bonded electrons and lone pairs of electrons result in different molecular shapes and (b) how unequal sharing of electrons within bonds along with the shape of a molecule result in polar and nonpolar molecules.
