Polar and nonpolar

A polar bond is a covalent bond between two atoms where the electrons forming the bond are unequally distributed. There is a difference in their
electronegativity. For example: oxygen has an electronegativity value of 3.5 and hydrogen is 2.1. When subtracting, their difference is 1.4. With this
example, this difference is big enough to make them a polar covalent bond However,the difference between nitrogen and hydrogen is only
most consider it nonpolar because it’s only by a small amount. A nonpolar covalent bond is a bond where the electronegativity between two atoms
are equal. This means they equal out to zero when you subtract them, OR are small enough of a difference, like nitrogen and hydrogen, to be
considered nonpolar.
