This episode dives into the predictable patterns of the periodic table, or "atomic trends," that help us understand how elements behave. It explains how properties like atomic radius (the size of an atom), electronegativity (its attraction for electrons), and ionization energy (the energy required to remove an electron) change as you move across a period or down a group. By breaking down these fundamental concepts, the episode provides listeners with the tools to predict an element's characteristics and how it will interact with other elements in chemical reactions.
