If you want to quickly find the word you want to search, use Ctrl + F, then type the word you want to search. The difference between the atoms is 1.24 which is between 0.50 and 2.00, so the molecule is a polar molecule. Polar "In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multipole moment. Polar Or Nonpolar? H2O polar in spades becasue of the bent shape The electronegativities of the five fluorine-phosphorus bonds cancel each other out, creating a nonpolar molecule. It is covalent (molecular). Q: Consider the following XF4 ions: PF4-, BrF4-, ClF4+, and AlF4-.
