Step 1I'll solve this problem by explaining the underlying atomic structure and electron configuration principles.
Step 2: Understanding Ionization Energy
Ionization energy is the energy required to remove the most loosely bound electron from a neutral atom in its ground state. The trend of increasing ionization energy across a period is related to several key atomic properties.
Final Answer
Ionization energy increases across a period due to increasing nuclear charge, decreasing atomic radius, and stronger electrostatic attraction between the nucleus and outer electrons, which makes removing an electron progressively more energy-intensive.
