I can memorize the periodic table, but understanding the trends is a whole different story. Ionization energy, electronegativity, electron affinity, and atomic radius—all these trends confuse me. I know that atomic radius decreases from left to right across a period, but I don’t understand why. The concept of effective nuclear charge and electron shielding is still murky. I also get confused about why ionization energy increases across a period but decreases down a group. For electronegativity, I understand the trend but I can’t explain it in exam answers using proper reasoning. I need a tutor who can use visual diagrams and analogies to make these trends stick. I want to see the periodic table as a map where each element’s properties are predictable based on its position. I need practice questions that ask “why” and not just “what” so I can build my conceptual understanding.
