When sodium metal reacts with water, the resulting heat melts the metal almost immediately into a grey-silver ball. The hydrogen gas evolved during this reaction propels the ball rapidly across the surface of the water, leaving a white trail of sodium hydroxide that eventually dissolves into a clear solution.

Similarly to the alkali metal oxides, alkaline earth metal monoxides combine with water to form metal hydroxide salts (as illustrated in the equation below). The exception to this general assumption is beryllium, whose oxide (BeO) does not react with water.

Most alkali metals and alkaline earth metals react with water to produce hydrogen. The alkali metals comprise Group 1 of the periodic table, and include lithium, sodium, potassium, rubidium, cesium and francium. The alkaline earth metals comprise Group 2, and include beryllium, magnesium, calcium, strontium, barium and radium.

Only metals above magnesium react with cold water to form the metal hydroxide and hydrogen. Choose an element for this reaction: | Potassium | Sodium | Calcium |. Reaction with hot water. Magnesium reacts slowly with hot water to give hydrogen and magnesium hydroxide.

This page looks at the reactions of the Group 1 elements - lithium, sodium, potassium, rubidium and caesium - with water. It uses these reactions to explore the trend in reactivity in Group 1. The Facts. General. All of these metals react vigorously or even explosively with cold water. In each case, a solution of the metal hydroxide is produced together with hydrogen gas. This equation applies to any of these metals and water - just replace the X by the symbol you want.

Magnesium (Mg) reacts with water vapor to form magnesium hydroxide and hydrogen gas. Beryllium (Be) is the only alkaline earth metal that does not react with water. This is due to its small size and high ionization energy in relation to the other elements in the group.

Potassium, sodium, lithium and calcium react with cold water, see alkali metals and alkaline earth metals. Metals in the reactivity series from magnesium to iron. react with steam - H2O(g) but not water - H2O(l). The reaction forms the metal oxide and hydrogen gas. You must know the test for hydrogen gas. magnesium + steam magnesium oxide + hydrogen.

In fact, boron (B) does not react at with water. One notable reaction within this group is aluminum's (Al) reaction with water. Aluminum does not appear to react with water because an outer layer of aluminum oxide (Al2O3) solid forms and protects the rest of the metal.

moon phases. Only metals above magnesium react with cold water to form the metal hydroxide and hydrogen. Magnesium reacts slowly with hot water to give hydrogen and magnesium hydroxide. Metals at the mid positions of the reactivity series react with steam to form the metal oxide and hydrogen.
