Difference between atom and molecule pdf
Section 8.5 • Electronegativity and Polarity 267 Therefore, in a molecule containing hydrogen and chlorine, the shared pair of electrons is with the chlorine atom more often than it is with the hydrogen atom. Symbols are used to indicate the partial charge at each end of the molecule from this unequal sharing of electrons. Polar Covalent Bonds As you just learned, polar covalent bonds
between two atoms will be ionic, covalent or metallic. Most covalent bonds have a degree of ionic character resulting from a difference in electronegativity between the atoms.
