Elements of group 1 (or IA) are known as alkali metals because their hydroxides are soluble in water and form strongly alkaline solutions. Alkali metals are stored under kerosene oil because they get tarnished on exposure to air. 2. The general electron configuration of alkali metals is ns1. 3. Alkali metals have largest size and lowest

It becomes too easy for drug abusers to lift a few prescription forms for illicit use if that number is easily available. The DEA number is
