In a nonpolar covalent bond, the electrons gather around...

• Mostly the atom with the greatest electronegativity

• The atom with the lowest electronegativity

• Each atom Equally

• Only the atom with the greatest electronegativity

The polarity of a bond is determined by...

• The sum of the electronegativities of the two atoms

• The difference in the electronegativities of the two atoms

• The charges of the atoms

• The number of electrons shared in the bond
