GEOLOGY

Detailed explanation-1: -Binary oxygen compounds containing electropositive metals are metallic oxides, while, those having nonmetals are non-metallic oxides. Metallic oxides: A chemical compound formed by metal and oxygen. Examples: Magnesium reacts with oxygen to form magnesium oxide.

Detailed explanation-2: -Oxides are chemical compounds with one or more oxygen atoms combined with another element (e.g. Li2O). Oxides are binary compounds of oxygen with another element, e.g., CO2, SO2, CaO, CO, ZnO, BaO2, H2O, etc. These are termed as oxides because here, oxygen is in combination with only one element.

Detailed explanation-3: -Metal oxides are binary compounds of oxygen with a metal. Inorganic oxides can be prepared by direct heating of elements with oxygen, reaction of oxygen with compounds at high temperatures, or oxidation of metals and non-metals with nitric acid.

Detailed explanation-4: -The reaction between a metal and oxygen gives metallic oxide as a product. These metallic oxides upon reaction with water form bases. Hence, the metallic oxides are considered as basic oxides.

Detailed explanation-5: -An oxide is a chemical compound that contains at least one oxygen atom and one other element. Dianion of oxygen is also called oxide which is represented by O-2.
