and its Characteristics Hydroxide is the name for the diatomic anion OH consisting of covalently bonded oxygen and hydrogen atoms usually derived from the dissociation of a base It is one of the simplest and most pervasive diatomic ions known. A homogenous, naturally occurring substance with definable internal structure is called mineral. .. Mode of occurrence of minerals:. (1) In igneous and metamorphic rocks: The smaller occurrences are called veins and the larger occurrences are called lodes. They are usually formed when minerals in liquid/molten and gaseous forms are forced upwards through cavities towards the earth’s surface. Examples: tin, copper, zinc, lead, etc..
