Group 2 elements, the Alkaline earth metals, become a +2 ion, and combine to make (OH)2 metal hydroxides. Any element in the first column (Group 1) of the periodic table will react violently with water. They get more explosive as you go down the column, so that means lithium, sodium, potassium, rubidium, caesium and francium will be more reactive, in that order. The elements in the second column (Group2) react less violently with water. And like the Group 1 elements, their reactivity increases as we go down the column. <br /><br />When added to water the Group 1 elements, the Alkali metals, becomes a +1 ion, and the water forms OH- (creating the metal hydroxide) and H2 gas.
metals like sodium,potassium and lithium are highly reactive metals which react vigorously with air at room temperature. the reaction is very exothermic. itthey can also be not stored in water as they react with water as well..so they are stored under kerosene to prevent the metal as well as any kind of destruction.ecause these are highly reactive metals and could catch fire by reacting with oxygen in the presence of air. ...........that 's why they are stored under oil to prevent their contact with oxygen.
