Alkali metals are extremely reactive because they 1. have very small atomic masses
2. are not solid at room temperature
3. have one valence electron that is easily removed to form a positive ion
4. have two valence electrons that form compounds with calcium and magnesium

Identifying limitations of kinetic-molecular theorya chemist is studying the properties of a gas under various conditions. he observes that when the gas is at room temperature and low pressure, it behaves as an ideal gas. when the gas is cooled to 10 kelvin and is placed under high pressure, however, it deviates significantly from an ideal .
