But, there is much more. They contain 1 to 3 valence electrons in the outermost shell of their atoms. Due to high electronegativity, oxygen can react with almost all the elements except noble gases. Non-metal oxides such as sulphur dioxide and nitrogen oxide are responsible for acid rain. Chemical Properties Of Nonmetals: Reaction With Oxygen – Nonmetals react with oxygen and form nonmetallic oxides which are acidic in nature. They contain 4 to 8 valence electrons in the outermost shell of their atoms. Non-metals are the elements wich are "generally" poor conductors of electricity and heat. You can determine if a particular solution is acidic or basic by testing with an acid-base indicator. In nature it is found as a base.

Answer Save. The change in character from acidic to basic can be explained on the basis of the size of atoms. Basic b. Materials which can be drawn into wires are called ductile. the litmus changes into red color. Since oxygen is highly reactive in nature, it reacts with metallic and non-metallic elements and forms oxides of those elements. Nonmetals have high ionization energies and electronegativities. This oxygen comes from either air or water. Basic oxides, also called base anhydrides, are compounds that can form a basic solution when dissolved in water.Basic oxides are formed as a result of the reaction of oxygen with metals. Non-metals react with oxygen to form acidic oxides, which dissolve in water to form acids. Nonmetals can have multiple oxidation states, both negative and positive. Nonmetals are soft.

The basic trend in oxide acidity across the rows of the periodic table is: Basic → Amphoteric → Acidic. The chemical property which can be used to distinguish between a metal and a nonmetal is the formation of positive ions by metals. Nonmetals generally have low melting and boiling point except for graphite. Here are two examples for the non-metals carbon and sulphur.
