Electronegativity: bond character/bond type: electronegativity difference and predicting bond type

In this video: What is electronegativity, what is electronegativity difference and how is it related to predicting different bond types: non-polar covalent, polar covalent, and ionic; What are the divisions in the continuum from minimum electronegativity difference to maximum difference and where do those divisions come from; How is bond type related to molecular character in terms of non-polar to polar.
