A Lewis dot structure is a drawing of a molecule. The drawing only “works” f0r stable molecules that actually exist. So it’s a nice tool to explore how atoms bond into more complex substances. A Lewis dot structure is also called a Lewis structure, a Lewis dot diagram, an electron dot structure, or a dot diagram. A Lewis structure is a graphic representation of the electron distribution around atoms. The reason for learning to draw Lewis structures is to predict the number and type of bonds that may be formed around an atom. A Lewis structure also helps to make a prediction about the geometry of a molecule. Demos Lewis Dot Structures. This demo will convert a skeletal figure, provided by a drawing in the HTML5 SketcherCanvas component on the left, into a Lewis Dot Structure in the Canvas on the right.

WRITING LEWIS DOT STRUCTURES Lewis structure or formula shows electron‐dot symbols for the atoms, the bonding pairs as lines, and the lone pairs that fill each atom's outer level (valence shell) as pairs of dots. Determine the total number of valence electrons. Add up the valence electrons of the atoms. Lewis Dot Structure (Electron Dot Structure) A Lewis dot structure is a quick and easy diagram that shows the valence electrons in an element. In a Lewis structure, the nucleus of the element is represented by its symbol. The valence electrons are represented by dots placed around the symbol in pairs.

A chemical element is identified by the number of protons in its nucleus, and it must collect an equal number of electrons if it is to be electrically neutral. As electrons are added, they fill electron shells in an order determined by which configuration will give the lowest possible energy. The first shell (n=1) can have only 2 electrons, so that shell is filled in helium, the first noble gas. In the periodic table, the elements are placed in 'periods' and arranged left to right in the order of filling of electrons in the outer shell. So hydrogen and helium complete the first period.

The number of electrons in a given shell can be predicted from the quantum numbers associated with that shell along with the Pauli exclusion principle. The second shell, associated with principal quantum number n=2, can have a maximum of 8 electrons and corresponds to the second period of the periodic table. The third shell also has 8 electrons, but things get more complicated after than because the subshells spread out enough that there is overlap between them.

Lewis Structures are important to learn because they help us predict:

• the shape of a molecule.
• how the molecule might react with other molecules.
• the physical properties of the molecule (like boiling point, surface tension, etc.).

That helps us understand and predict interactions with things like medicine and our body, materials used to make buildings and airplanes, and all sorts of other substances. Lewis structures don't tell us everything, but along with molecule geometry and polarity they are hugely informative.
