What is the chemical composition of minerals?

The composition of a mineral can be expressed as a CHEMICAL FORMULA, which simply gives the proportions of the different elements and groups of elements in the mineral. The latter notion (groups of elements) comes into play for those minerals which have a restricted range of composition.

What are the 7 composition of minerals?

Introduction. Minerals are grouped by their chemical composition. Silicates, oxides, sulfates, sulfides, carbonates, native elements, and halides are all major mineral groups.

What is the classification of minerals based on composition class 8?

The classification system known as the Dana system is most commonly used. In this system, minerals are classified into eight main mineral groups based on chemical composition. These classes are: native elements, silicates, oxides, sulfides, sulfates, halides, carbonates, phosphates, and mineraloids.

What is the important of classifying minerals based on their chemical properties?

Because the physical properties of a mineral are determined by its chemical composition and internal atomic structure, they can be used diagnostically, the way a runny nose and sore throat can be used to diagnose a cold.

What is chemical composition?

Chemical composition refers to the arrangement, type, and ratio of atoms in molecules of chemical substances. Chemical composition varies when chemicals are added or subtracted from a substance, when the ratio of substances changes, or when other chemical changes occur in chemicals.

What are the chemical properties of minerals?

Minerals can be identified using a number of properties. These include physical and chemical properties such as hardness, density, cleavage and colour, crystallography, electrical conductivity, magnetism, radioactivity and fluorescence.

How do you classify minerals according to their physical and chemical properties?

Most minerals can be characterized and classified by their unique physical properties: hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity.

What is the two types of mineral according to chemical properties?

Minerals are divided into two types namely metallic and non-metallic.
  • Metallic Minerals. Metallic minerals exhibit lustre in their appearance and consist of metals in their chemical composition. …
  • Non-metallic minerals. Non-metallic minerals are minerals which either show a non-metallic lustre or shine in their appearance.
