Hydrogen (Class 11): Position, Isotopes, Hydrides and Water
Class 11 · Chemistry Hydrogen (Class 11): Position, Isotopes, Hydrides and Water An element that fits nowhere neatly, which is exactly why its placement is such a common question. Class 11 · CBSE & ISC · Concept The short answer: Hydrogen resembles both group 1 and group 17, which is why its position is anomalous. Its compounds with other elements fall into three hydride classes determined by electronegativity difference, and hard water, heavy water and hydrogen peroxide are the specific topics most often examined. Why its position is anomalous Resembles group 1 because Resembles group 17 because One electron in…
