We’re asked to decide whether each molecule or polyatomic ion is polar or nonpolar. If it is polar, we have to write the symbol of the atom closest to the negative side of 3 molecules or polyatomic ions shown in the table.
Remember that molecules that have unequal sharing of electrons contain a molecular polarity. This is determined using Lewis structures.
For a nonpolar molecule:
If the central element has no lone pairs, it must be connected to the same surrounding elements.
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 HCl and you decided the hydrogen atom was closest to the negative side of the molecule, you'd enter "H" in the last column of the table.
