Indicate the ionization energy trend observed: a) along the rows (periods) of the periodic table it increases progressively b) down the columns (groups) of the periodic table first ionization energy decreases constantly 4 marks 3. How many electrons must aluminum lose before it can reach a stable electronic configuration? Use the table of ionization energy to justify your answer. Aluminum must loose three electrons before it reaches a stable electronic configuration. This is shown in the ionization table by the very large increase in the ionization energy jump between the 3 rd and 4 th ionization energy levels. 3 marks 4. Prepare a report on the experiment you’ve completed. It should include: the aim of the experiment, the observations drawn and the questions raised. For sodium and potassium, don’t copy all the observations given to
