Question

TestHub · Accepted Answer

Beryllium does not react with water or steam even at high temperatures due to its high ionization enthalpy and small size.

Other alkaline earth metals like Magnesium, Calcium, Strontium, and Barium react with water to form their respective hydroxides and liberate dihydrogen gas. Magnesium reacts with hot water, while Calcium, Strontium, and Barium react with cold water.

Therefore, Beryllium is the element that does not form its hydroxide and dihydrogen with water.
