Check the electronegativities of the atoms in the bond. The bond will be polar if there is a difference in electronegativity. The most electronegative element will attract the bonding eletrons to it becoming slightly negatively charged. The other end of the bond will become slightly positively charged. For example a bond between carbon and chlorine, C-Cl:
C electronegativity 2.55
Cl electronegativity 3.16
The bond will be polar because of the difference in electronegativity, and Cl will be slightly negative, carbon slightly positive.
Polar=distinguishable + and - sides
non-polar=neutral or completely + or completely -
Be and Cl form an ionic bond (BeCl2), and it is polar.
When one pair of electrons is shared, a single covalent bond exists. This bond can be either polar or nonpolar. If the electrons are equally shared, the bond is nonpolar. If the electrons are unequally shared, the bond is polar.
A nonpolar bond could only occur with covalent bonds, as all ionic bonds are polar. This means that all elements involved in nonpolar bonds are nonmetals.
nonpolar or polar
C-H bond of it is polar.CH4 has four such bonds
nonpolar!
Nonpolar covlalent bond
The bond in boron trichloride, BCl3, is polar covalent.
polar
Hydrogen gas, H2, is nonpolar because both hydrogen atoms have the same electronegativity, so the difference in electronegativity is 0, which means the bond is nonpolar, and since this is the only bond, the gas is nonpolar.

Nonpolar (:
it is nonpolar since C-H bonds are considered a nonpolar bond
It is non polar
This bond is nonpolar covalent.
A covalent bond in which electrons are shared unequally is polar.The valance electons are shared equally and the bond is nonpolar.
It can be either a polar covalent bond or a nonpolar covalent bond. C-Cl is an example of a polar covalent bond, while C-C is a good example of a nonpolar covalent bond.
