Hydronium is an abundant molecular ion in the interstellar medium and is found in diffuse and dense molecular clouds as well as the plasma tails of comets. When H+ is removed from water molecule, the shared pair of electron remains with oxygen as oxygen is more electronegative and thus hydroxyl ion has negative charge. (H = 1; O = 8).
