It is known that silicon forms compounds with 64 out of the 96 stable elements and possibly form silicides with other 18 elements. Appart from metallic silicides, which are used in big quantities in metallurgy, it forms important commonly used compounds with hydrogen, carbon, halogens, nitrogen, oxygen and sulphur.
gen atom. The chemical and physical properties of a substance refer to measurable or observable qualities or attributes that are used to distin-guish between different substances. Chemical properties describe how a substance interacts with other matter. Sodium and potassium, for example, react with water, but aluminum and gold do not. Physical properties are descriptive characteristics of matter. Examples of physical properties include color, density, conductivity, and malleability. Every substance will have a unique set of chemical and physical properties that can be used to identify it, because every type of substance has a unique atomic composition. It is often challenging to determine the identity of an unknown substance based on its chemical and physical properties.
