   Feb 5, 2024 · Reactions of the oxides of group 2 elements with water. Group 2 ionic oxides react with water to form hydroxides. The ionic oxides are basic as the oxide ions accept protons to become hydroxide ions in this reaction (acting as a bronsted lowry base) MgO (s) + H2O (l) Mg(OH)2 (s) pH 9.

   What is a group 2 compound?

   • Compounds formed by Group 2 elements are typically white solids that are insoluble in water. When reacted with oxygen, the metals form oxides: for example, 2Mg + O2 → 2MgO. With water, these elements form hydroxides and release hydrogen gas: for instance, Mg + 2H2O → Mg (OH)2 + H2.

   What is a group 2 isotope?

   • Each Group 2 element forms one stable, naturally occurring isotope, except for Beryllium and Radium. The atomic and ionic radii of Group 2 elements increase down the group; this is due to an increased number of electron shells.

   Why does Group II reactivity increase down the group?

   • The atomic radius of group II metals increases down the group due to additional electron shells. Increased electron shielding down the group makes the outer electrons easier to lose. Therefore reactivity of the group II metals increases down the group.

   Why are Group II metals called alkali metals?

   • Therefore the melting points decrease down the group. The group II metals react with water in a redox reaction to produce a metal hydroxide and hydrogen. The metal hydroxide form as an alkaline solution, hence why the group II metals are known as the alkali metals. The magnesium is oxidised from OS (oxidation state) 0 to OS +2.

   Why is beryllium a group 2 metal?

   • Beryllium is unique among the Group 2 metals because it does not react directly with water or any compound containing the hydroxide (OH) ion. Each Group 2 element forms one stable, naturally occurring isotope, except for Beryllium and Radium.

   Why do Group II metals reactivity decrease down the group?

   • Therefore reactivity of the group II metals increases down the group. The first ionisation energy of group II metals decreases down the group due to a greater atomic radius and increased amounts of shielding.
