Drawing Lewis structures for molecules with one central atom: five steps to success. The following procedure will give you the correct Lewis structure for any molecule or polyatomic ion that has one central atom. Step 1: Figure out how many electrons the molecule must have, based on the number of valence electrons in each atom. When drawing the ...

This is a whiteboard animation tutorial on how to draw Lewis structures of molecules.
This chemistry video provides a basic introduction into how to draw lewis structures of common molecules such as Cl2, O2, OF2, CH4, NH3, H2O, C2H2, and N2H4....
Lewis structures are drawn by a series of dots, lines, and atomic symbols and provide a structure for the way that the atom or molecule is arranged. A Lewis Dot Structure can be made for a single atom, a covalent compound, or a polyatomic ion.
Learn how to draw a Lewis structure to show the bonding and valence electrons in a molecule. See why Lewis structures are important.
Writing Lewis Structures. Determine the total number of valence (outer shell) electrons. For cations, subtract one electron for each positive charge. For anions, add one electron for each negative charge. Draw a skeleton structure of the molecule or ion, arranging the atoms around a central atom.
Here's how I draw Lewis structures. You count the valence electrons. Count the valence electrons for each atom, add them up, and add or remove electrons if there is an overall charge.
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 predict the geometry of a molecule.
A Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds. The Lewis structure was named after Gilbert N. Lewis, who introduced it in his 1916 article The Atom and the Molecule.
