Ionization Energy is the energy required to remove an electron from a gaseous atom or ion. 

Ionization Energy

Concept #1: Ionization Energy (IE)

Concept #2: Periodic Trend: Ionization Energy

Moving towards the top right corner of the Periodic Table causes ionization energy to increase.

Example #1: Which of the following atoms has the smallest ionization energy?

Practice: Rank the following elements in order of increasing ionization energy: Br, F, Ga, K and Se.

Practice: Which of the following elements would lose an electron the easiest?

Practice: Which element from Group 7A has lowest ionization energy.

Practice: Which of the following has the highest ionization energy?
