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
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.
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
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
