Decide whether each molecule or polyatomic ion is polar or nonpolar. If the molecule or polyatomic ion is polar, write the chemical symbol of the atom closest to the negative side. For example, if the molecule were HCI and you decided the hydrogen atom was closest to the negative side of the molecule, you'd enter ":" in the last column of the table. alo H molecule or polyatomic ion polar or nonpolar? atom closest to negative side O polar O nonpolar HI O polar O nonpolar H,S O polar CH, O nonpolar

The the geometry of individual molecules from the number of electron pe surrounding their central atoms. A molecule consisting of only two atoms has atoms bonded to the central shape. A molecule with atom with molecule with atoms bonded to the central atom with unshared pair(s) of electrons has a trigonal planar shape. The measure of the degree of inequality in the attraction of bonding electrons to various locations within a molecule is called there is an equal sharing of electrons between the two atoms. While a molecule may be A molecule may be when when it has a net dipole as a result of the opposing charges.
