A
- Non-polar bonds
- Polar bonds

Q
What are non-polar bonds?
A
Non-polar bonds are formed between atoms of the same electronegativity, usually the same atom. Meaning that the electrons are evenly shared between the atoms, e.g. fluorine molecule.

Q
What are polar bonds?
A
Polar bonds are formed between atoms of differing electronegativity. Meaning that the electrons aren’t evenly shared between the nuclei but are attracted to more electronegative element to a greater degree.
This results in a positive ‘end’ & a ‘negative’ end’ or positive and negative dipoles.
E.g. Hydrogen fluoride - Fluorine is more electronegative (has more electrons) than hydrogen.
