To determine the type of bond any two atoms will form, find the difference between the electronegativities
between the two atoms. The diagram below shows what type of bond will form between two atoms based
on the electronegativity difference. Polar covalent bonds can be weak (>0.5 - 1.0) or strong (>1.0-2.0).
