Electronegativity & Polarity
Using Electronegativity To Determine Bond Type
In this video we'll introduce the concept of electronegativity -- basically how big of an electron hog each element is and how well it shares with others -- and use it to determine if bonds are nonpolar covalent, polar covalent, or ionic.
Determining If Molecule Is Polar
Even if the individual bonds which make up a molecule are polar, you can still have a molecule which is overall nonpolar because all the little dipoles cancel each other out. In this video we'll use everything we know about Lewis Structures, molecular shape, and electronegativity to determine if molecules are polar.
