Which trend is observed in ionization energy across a period in the periodic table?

Which trend is observed in ionization energy across a period in the periodic table?

Step 1: Understand what ionization energy is. It is the energy required to remove an electron from an atom.
Step 2: Know that the periodic table is organized in rows called periods.
Step 3: Observe that as you move from left to right across a period, the number of protons in the nucleus increases.
Step 4: Realize that more protons mean a stronger positive charge in the nucleus.
Step 5: Understand that a stronger positive charge pulls electrons closer to the nucleus.
Step 6: Conclude that because the electrons are held more tightly, it takes more energy to remove them.
Step 7: Therefore, ionization energy increases as you move from left to right across a period.
