Examples of polar elements include oxygen and nitrogen, which have a nonzero dipole moment due to their difference in electronegativity. Nonpolar elements such as helium and neon have symmetric charge distributions, resulting in no net dipole moment.
Nonpolar like all diatomic elements
Predicting if a covalent compound will be polar or nonpolar based on the elements' positions on the periodic table involves comparing their electronegativities. If the electronegativities of the atoms are similar, the bond is nonpolar. If there is a significant electronegativity difference between the atoms, the bond is polar.

HBF2 is polar. This is because the bond between hydrogen and fluorine creates a dipole moment due to the electronegativity difference between the two elements.
