Lesson 4: Ionization Energy & Electronegativity

Match the vocabulary word to its definition.

• Electronegativity

• How attracted an atom's nucleus is to the outer electron shell.

• Attraction

• The ability of an atom to attract shared electrons from another atom in a bond.

• Ionization Energy

• The energy required to remove an electron from the outer electron shell.
