Orbital Hybridization
Orbital Hybridization Orbital hybridization controls the local geometry around an atom. More than any other factor, the hybridization state of electron orbitals is responsible for the shape of molecules. Solitary atoms undergo orbital hybridization under the influence of… Read More
Electron Configurations: First Three Rows
Electron Configurations Up To 3rd Period The electron configurations and orbital diagrams of the first three rows (periods) of the periodic table occupy an important role. The configurations form the basis of chemical behavior. Periodic Table to Electron… Read More
Electron Shells and Orbitals
Electron Shells Electron shells and orbitals hold electrons in a specific pattern. In a neutral atom, the number of electrons must equal the number of protons. This makes the number of electrons equal to an element’s atomic number. The electrons… Read More
Molecular Shape
Molecular Shape Important The structure of a molecule is not complete until you know the molecular shape. Molecules which have seemingly an identical molecular shape often have very different chemical properties. The featured image above shows a… Read More
Polar Molecule and Nonpolar Molecule
The difference between a polar molecule and a nonpolar molecule depends on molecular geometry. Polar Bonds Polar result when two different elements share electrons and form a covalent bond. Each element has a characteristic electronegativity. A more electronegative element… Read More
Electronegativity and Polarity
Bond polarity comes from different elements having different electronegativity; the innate ability to attract electrons within a covalent bond. Electronegativity Each element has a value for electronegativity to compare how two atoms distribute negative charge when they share electrons.… Read More
Dimensional Analysis in Chemistry
One of the first road blocks you might find when you start chemistry is how to do dimensional analysis problems. Dimensional analysis problems do not lend themselves to memorization. The first factor of frustration comes when… Read More

How to Study Chemistry
After so much advice on how to study chemistry, it is obvious a lot of “information” is not really helpful. What You Usually Hear There must be better advice than “to study more” , “remove distractions”, “eat well”, “make a… Read More
