Polarity of chemical bonds

What determines the polarity of a chemical bond?

• The difference in electronegativity between the two atoms

• The atomic mass of the atoms

• The number of protons in the atoms

• The temperature of the environment

What happens to the electrons in a polar covalent bond?

• They are shared unequally between the atoms

• They are shared equally between the atoms

• They are completely transferred to one atom

• They are lost to the environment
