Lewis StructuresPhoto by: ImagewellIn 1902, while trying to find a way to explain the Periodic Table to his students, the chemist Gilbert Newton Lewis discovered that the chemistry of the main-group elements could be explained using a model in which electrons arranged around atoms are conceived ...

Lewis StructuresWe also use Lewis symbols to indicate the formation of covalent bonds, which are shown in Lewis structures, drawings that describe the bonding in molecules and polyatomic ions. For example, when two chlorine atoms form a chlorine molecule, they share one pair of electrons:...
Learn about Lewis dot structures and see their resonance in this engaging video lesson. Master ways to draw atoms and molecules, then take a quiz for practice.
This is the same amount of electrons as the number of valence electrons that oxygen atoms have on their own, and as such both of these oxygen atoms have a formal charge of zero. The two oxygens with the single bonds to sulfur have seven electrons around them in this structure (six from...
The octet rule states that, except for hydrogen and helium (each of which has a full valence shell when it has two electrons), elements are at their most stable states when their valence shell contains eight electrons. As a result, atoms and ions are less reactive when they have a full ...
Lewis structures (Lewis, 1916) are the simplest model to get students started in the use of atoms and bonds – the basic semantic units of the chemical symbolic language – to efficiently communicate chemical information. Competence in their use is essential to progress in the study of chemistry...

This article presents a journey through a sequence of steps designed to transform novices into experts in constructing Lewis structures. The progression begins with the decoration of central atoms, moves to the connection of central and terminal building blocks, and culminates in pattern recognition. ...
