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.
When any pure metal from Group 1 of the periodic table comes into contact with water, the water, which is H2O, is torn apart in the reaction, and two things will happen. First hydrogen gas will be liberated, and second, OH ions (hydroxide ions) will be formed when they combine with the metal.(It'll get plenty hot, too.) The metal atoms have loaned an electron to the OH part of water to make it OH-, our hydroxide ion.hen any pure metal from Group 1 of the periodic table comes into contact with water, the water, which is H2O, is torn apart in the reaction, and two things will happen.
