electrons that are equally shared and not equally shared
What are polar covalent bonds?
electrons not equally shared
what are electrons that are not equally shared by two atoms?

What is an ionic bond?
a weak bond, electrons are being completely transferred from one atom to a different atom, forming bond, which are attracted to each other
