increasing ionization energy

Explanation:

Ionization energy trends are based on atomic structure. Moving up a group reduces electron - shielding and increases effective nuclear charge. Moving right across a period increases the number of protons and effective nuclear charge while electrons are added to the same shell.

Answer:

The ionization energy of elements increases moving UP each group and RIGHT across each period.
