Construct a Lewis Structure St. Olaf College
Starting with a structure indicating only atom connections (single bonds), you can practice constructing a Lewis dot structure. Just click on the atom or bond you wish to modify.

AN EXPERIMENT USING MOLECULAR MODELS chymist
Essentially, all organic molecules obey the octet rule, and so do most inorganic molecules and ions. For species that obey the octet rule it is possible to draw electron dot, or Lewis, structures.
Oxidation reduction reaction Oxidation states ...
Oxidation states. The idea of assigning an oxidation state to each of the atoms in a molecule evolved from the electron pair concept of the chemical bond.
The octet rule is a chemical rule of thumb that reflects observation that atoms of main group elements tend to bond in such a way that each atom has eight electrons in its valence shell, giving it the same electron configuration as a noble gas.
