Class 11 · Chemistry s-Block Elements (Class 11): Alkali and Alkaline Earth Metals Two groups whose entire chemistry follows from one trend — size increases down the group, and almost everything else follows from that. Class 11 · CBSE & ISC · Concept The short answer: Down both groups, atomic size increases, ionisation energy falls and reactivity rises. The first element of each group is anomalous because of its small size and high charge density, and shows a diagonal relationship with the second element of the next group. The trends, and the one cause behind them Down a group, each…
