  3. Entry Task • Represent the Ionization of Potassium (K): • Represent the Dissociation of Magnesium Chloride (MgCl2) • K 0 + IEK1+ + e- MgCl2(s) Mg 2+(aq) + 2 Cl-(aq) + IE 19e- 19p+ 18e- 19p+ + e-

  4. Entry Task • Would you expect the Ionization Energy of Chlorine (Cl) to be higher or lower than the Ionization Energy of Radium (Ra). Explain. Higher. Remember the trends of I.E. in the Periodic Table. As you move from the left to the right IE increases, as you move from top to bottom IE decreases.

  5. Trends in Ionization Energy Ionization Energy Increases Highest I.E. Ionization Energy Decreases Lowest I.E.

  6. Electronegativity • Covalent bonds form when atoms have similar electrical properties. • Ionization energy is one way to quantify those electrical properties • Electronegativity is another way to quantify electrical properties.

  7. Electronegativity • Electronegativity is the ability of an atom to attract electrons. • The higher the electronegativity, the more strength the atom has to pull electrons toward itself. • Ionization: the process of removing an electron from an atom
