WebTHE THEORY of ACIDS and ALKALIS and a few technical terms: oAcidsare substances that form hydrogen ions (H+ (aq) ) when dissolved in water eghydrochloric acid HCl gives H+ (aq) and Cl - (aq) ions, sulphuric acid H 2 SO 4 gives 2H+ (aq) and SO 4 2-ions and nitric acid HNO 3 gives H + (aq) and NO 3 - (aq) WebAug 21, 2024 · All the elements in Group 2 have two electrons in their valence shells, giving them an oxidation state of +2. This enables the metals to easily lose electrons, which increases their stability and allows them to form compounds via ionic bonds. The following diagram shows the location of these metals in the Periodic Table:
