To draw the Lewis structure of an atom, write the symbol of the atom and draw dots around it to represent the valence electrons. Note that hydrogen is often shown in both group 1A and group 7A, but it has one valence electron – never seven.

- 9.2: Lewis Electron Dot Diagrams
Lewis structures (also known as Lewis dot structures or electron dot structures) are diagrams that represent the valence electrons of atoms within a molecule. These Lewis symbols and Lewis structures help visualize the valence electrons of atoms and molecules, whether they exist as lone pairs or within bonds.
In this section, we will explore the typical method for depicting valence shell electrons and chemical bonds, namely Lewis symbols and Lewis structures. Lewis Symbols We use Lewis symbols to describe valence electron configurations of atoms and monatomic ions.
Learn how to draw Lewis dot structures for atoms with up to 20 valence electrons, including carbon. See examples of covalent bonding and how to use Lewis structures to describe compounds.
A Lewis electron dot diagram (or electron dot diagram, or a Lewis diagram, or a Lewis structure) is a representation of the valence electrons of an atom that uses dots around the symbol of the element.
Here's some of the guidelines for drawing dot structures. So let's say we wanted to draw the dot structure for this molecule, so silicon tetrafluoride. The first thing we would need to do is to find the total number of valence electrons. And we would account for these valence electrons in our dot structure.
Both the oxygen and the carbon now have an octet of electrons, so this is an acceptable Lewis electron structure. The O has two bonding pairs and two lone pairs, and C has four bonding pairs. This is the structure of formaldehyde, which is used in embalming fluid.
