What is the chemical property of mineral?

Asked by: Kelly Tansky

What are chemical property of minerals?

Properties that help geologists identify a mineral in a rock are: color, hardness, luster, crystal forms, density, and cleavage. Crystal form, cleavage, and hardness are determined primarily by the crystal structure at the atomic level. Color and density are determined primarily by the chemical composition.

What is physical and 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.

What is the chemical structure of a mineral?

The atoms in a mineral are arranged in an organised ‘atomic structure‘. They connect together to form molecules, and the molecules stack together in a regular pattern to form a crystal. The shape of a crystal depends on the way the molecules are stacked up inside it.

What is chemical mineral?

In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid chemical compound with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form.

What is the physical properties of mineral?

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

What are the 5 properties of minerals?

Minerals can be identified by their color, luster, streak, cleavage, hardness, and even by their chemical composition.

Why do minerals have different chemical properties?

Answer and Explanation: Minerals have different properties because they are made out of different elements. Minerals can be made of silicon, carbon, phosphorus, oxygen, iron, calcium, magnesium, and many other native elements. These native elements have different properties based on how many electrons they have.

Why do minerals differ in physical and chemical properties?

The atoms are arranged in the same way in every piece of salt. Sometimes two different minerals have the same chemical composition. But they are different minerals because they have different crystal structures.

Why does a mineral have a definite chemical composition?

Definite Chemical Composition means that all occurrences of that mineral have a chemical composition that varies within a specific limited range and the atoms that make up the mineral must occur in specific ratios.

Are all minerals chemical compounds?

Although most minerals are chemical compounds, a small number (e.g., sulfur, copper, gold) are elements. Minerals combine with each other to form rocks. For example, granite consists of the minerals feldspar, quartz, mica, and amphibole in varying amounts.

Is a mineral has definite chemical composition?

A mineral is a naturally occurring inorganic solid, with a definite chemical composition, and an ordered atomic arrangement.

What is the chemical compound of rocks?

Most rocks contain silicate minerals, compounds that include silica tetrahedra in their crystal lattice, and account for about one-third of all known mineral species and about 95% of the earth’s crust. The proportion of silica in rocks and minerals is a major factor in determining their names and properties.

How are the physical and chemical properties of rock determined?

All rock has physical and chemical properties that are determined by how and where the rock formed. The rate at which rock weathers and the way that rock breaks apart are determined by the chemical stability of the minerals in the rock.

Which one is not physical property of mineral?

Presence of Sulphides is not a physical property with respect to the minerals.

What are the two major properties of mineral?

A mineral species is defined by two distinct properties: (1) its chemical com- position and (2) its crystal structure.

Why do minerals have different chemical properties?

Answer and Explanation: Minerals have different properties because they are made out of different elements. Minerals can be made of silicon, carbon, phosphorus, oxygen, iron, calcium, magnesium, and many other native elements. These native elements have different properties based on how many electrons they have.

Are minerals Chemicals?

“A mineral is a naturally occurring chemical compound, usually of crystalline form and abiogenic in origin. A mineral has one specific chemical composition, whereas a rock can be an aggregate of different minerals or mineraloids.

What are the two 2 major properties of minerals?

A mineral species is defined by two distinct properties: (1) its chemical com- position and (2) its crystal structure.

What are the 7 types of minerals?

The major classes of minerals are given below:

• silicates.
• sulfides.
• carbonates.
• oxides.
• halides.
• sulfates.
• phosphates.
• native elements.

Is Diamond a mineral?

diamond, a mineral composed of pure carbon. It is the hardest naturally occurring substance known; it is also the most popular gemstone. Because of their extreme hardness, diamonds have a number of important industrial applications.

Is water a mineral?

Water does not pass the test of being a solid so it is not considered a mineral although ice; which is solid, is classified as a mineral as long as it is naturally occurring. Thus ice in a snow bank is a mineral, but ice in an ice cube from a refrigerator is not.
