Mission MAM9 Ionization Energy as a Periodic Trend

Mission MAM9 pertains to the periodic trends associated with ionization energy (IE). Students must apply the trends to compare the relative IE of triads of elements. The mission consists of 28 questions organized into 7 Question Groups.

Learning Outcomes

  • The student should be able to describe the across-a-period and down-a-group trends in the ionization energy of elements.
  • The student should be able to use the modern model of the atom to explain the periodic trends in ionization energy.
