Bond Polarity

Answer 1

How do you determine bond polarity? I sort of understand it, but not quite

How do you determine bond polarity?
You need a fairly detailed periodic table to do a specific finding.
Labeled per element is an electronegativity reading. To determine the bond type, you need to subtract one element's reading from the other (usually the smaller from the larger). I think the general consensus is any difference above 7 is considered ionic and anything above 1.5 is polar covalent.

For example, in O2, the electronegativity difference is 0. Since 0 < 1.5, that means the bond is nonpolar covalent.
