Today's lesson was over bond polarity and different types of bonds. Polarity occurs when electrons aren't shared equally between two atoms. When the electrons are shared unequally, one electron has a stronger pull on the bond as a result of differing electronegativities. Between the electrons in an atom, one of three different types of bonds forms: nonpolar covalent, polar covalent, or ionic. Nonpolar covalent occurs when the two electrons are shared equally between the atoms. Polar covalent is the result of unequally shared electrons that cause a partial charge on the atoms. Lastly, ionic bonds are formed when a complete transfer of electrons occurs giving full charges on the resulting ions.
