Alkali and Alkaline Earth Metals - TechnologyUK
Essentially, the heavier the alkaline earth metal, the more vigorously it will react with water. The alkaline earth metals (highlighted) occupy group two in the periodic table Magnesium is the fifth most abundant element on earth, closely followed by calcium in eigth place - which is just as well, since both magnesium and calcium are vital to all living things, including human beings!
Why Sodium And Potassium Really Explode In Water
They recognized that the steam and hydrogen generated early on in the reaction should form a buffer layer over the metal surface and impede water from continuing to react.
Metals And Non Metals - Meritnation: The …
Answer: When metal M 3 is reacted with a salt of metal M 4 then it displaces metal M 4 from its salt solution and salt of metal M 3 is formed. But when metal M 4 is reacted with a salt of metal M 3, no reaction takes place.Hence, metal M 3 is more reactive than metal M 4, because it displaced metal M 4 from its salt solution but metal M 4 could not displace metal M 3 from its salt solution.

Water-reactive substances - Wikipedia
The alkali metals (Li, Na, K, Rb, Cs, and Fr) are the most reactive metals in the periodic table - they all react vigorously or even explosively with cold water, resulting in the displacement of hydrogen.The Group 1 metal (M) is oxidised to its metal ions, and water is reduced to hydrogen gas (H 2) and hydroxide ion (OH −), giving a general equation of:
