How do electronegativity values help us determine the type of bond created?

Electronegativity values of atoms enable us to determine if and to what extent electrons are being shared equally or unequally and thus allows us to determine if a bond is ionic, nonpolar covalent, or polar covalent.

What does electronegativity mean?

How well/strongly an atom attracts electrons in a bond to themselves.

How are ionic bonds and covalent bonds different?

Ionic bonds are bonds that occur when the electronegativity difference between two atoms in a bond is so great that there is a complete transfer of electrons from one atom to another, while covalent bonds occur when electrons are shared in a bond between two atoms.

Define polar and nonpolar bonds using complete sentences. In your definition, make it clear what criteria you use to determine if a bond is polar or nonpolar.

Polar: When electrons being shared in a covalent bond are shared relatively unequally. Nonpolar: Occurs when electrons being shared in a covalent bond are shared relatively equally.
