Explanation:

Thank you Michael for finding the data and showing that the question uses an incorrect statement (see comments).

In general, the first ionisation energy of an atom increases as you move across a period in the periodic table. This is because more protons are added to the nuclei of the atoms and so the nuclear charge of the atoms increases. The electrons in the outer energy levels will be more strongly held, and so difficult to remove - thus resulting in a higher ionisation energy.
