This means that the alkali metals all have similar chemical properties. All of Group 1 elements—lithium, sodium, potassium, rubidium and cesium react vigorously or even explosively with cold water. alkaline earth metals noble gases alkali metals halogens. Which two elements react most vigorously with each other? (Potassium actually is the more reactive of the two) The reason is that potassium and sodium both lie in Group 1 of the periodic table, which contains all the alkali metals. All of these metals react vigorously or even explosively with cold water. All the alkali metals react vigorously with halogens to produce salts, the most industrially important of which are NaCl and KCl. Hence chlorine and potassium will react more violently. Group 1 Group 2 Group 3-12 Group 15 Group 16 Group 17 Group 18 . How do they react with water? A salt is formed MBr2 B. The non-metal elements in Group 7 – known as the halogens – get less reactive as you go down the group. New questions in Chemistry. Feb 5, 2014 . Related questions.
