POLARITY We've already talked about electronegativity and how to predict whether a bond is polar or nonpolar. For example: Pure covalent bond = sharing of electrons between two identical atoms (with the same electronegativity and no difference in charge) i.e. O2 Polar covalent bond = sharing of electrons between two or more different atoms with a difference in electronegativity. i.e. HCI Just as a bond can be polar or nonpolar, we can also classify an entire molecule as polar or...
