How can you tell when a molecule is a polar covalent bond and a nonpolar covalent bond? and Bond

How can you tell when a molecule is a polar covalent bond and a nonpolar covalent bond?



I know that a nonpolar covalent bond the sharing of electrons between two atoms is equal and the polar is not, but what does that mean? How can i tell?


Bond best answer:

Answer by Apathy
Look at Electronegativity, that means how strong an element takes in an electron. Fluorine has the highest electronegativity in the periodic table. That means say it bonds with a weak atom like Hydrogen to form hydrogen fluoride, which is polar covalent, anyways, the fluorine is so strong at taking the electrons from H that it acts like a bully and thus is more electronegative end than the H. Good Luck! :D

Edit: Also diatomic molecules like H2, F2, etc, are equal and thus are nonpolar covalent.

*Tip: Electronegativity increases from left to right and from the bottom up.
