Identify Element with Highest Ionization Energy

Consider the following statement about elements in the periodic table:

Elements are arranged in a specific order based on their atomic number, which reflects the number of protons within the nucleus of an atom. As you move from left to right across a period, the atomic number increases, and so does the nuclear charge. This trend affects various properties of elements, including their ionization energy.

Which of the following elements has the highest ionization energy?
