What else can I help you with?
What is both a mineral and a substance?
Diamond is both a mineral, composed of carbon atoms arranged in a crystal lattice, and a substance known for its hardness and brilliance.
What is the streak luster hardness and crystal system of petroleum?
Petroleum is a liquid mixture of hydrocarbons. It does not have a streak luster, hardness, or crystal system as it is not a mineral but rather a naturally occurring substance derived from organic matter.
Is crystal shape a physical property?
Yes, crystal shape is a physical property. It refers to the external geometric form that a crystal takes, which is determined by the arrangement of atoms within the crystal lattice. The shape of a crystal can provide information about its internal structure and symmetry.
Does the Mohs scale help scientists identify the crystal shape of a mineral?
The Mohs scale is a measure of hardness, not crystal shape. Crystal shape is determined by the internal arrangement of atoms in a mineral and is usually identified using X-ray crystallography or microscopy techniques.
What is the name of the substance in diamonds?
The name of the substance in diamonds is carbon.
What is the hardest substance on the earth that is non metal?
Diamond is the hardest substance on Earth that is non-metal. It is made of carbon atoms arranged in a strong crystal lattice structure, giving it its extraordinary hardness.
How do you account the differences in hardness of the crystal?
nothing
Hardest known substance?
Diamond is the hardest known natural substance, with a score of 10 on the Mohs scale of mineral hardness. It is made up of carbon atoms arranged in a crystal lattice structure, giving it its exceptional hardness and durability.
Which natural substance on earth is the hardest?
Diamond is the hardest natural substance on Earth, ranking 10 on the Mohs scale of mineral hardness, due to its tightly packed carbon atoms in a strong crystal lattice structure.
Is soft metal chemical property?
Softness is a physical property of metals, not a chemical one. The softness of a metal is determined by its crystal structure and the presence of defects or impurities in the metal's lattice structure, rather than its chemical composition.
Which mineral property depends on bond type and the spacing of atoms within the crystal?
Cleavage is the mineral property that depends on bond type and the spacing of atoms within the crystal. Cleavage is the tendency of a mineral to break along specific planes of weakness due to the arrangement of atoms and the type of chemical bonds holding them together.
How do you account for observed differences in hardness of the crystals?
Observed differences in crystal hardness can be attributed to variations in the arrangement of atoms within the crystal lattice, impurities present in the crystal structure, temperature of crystallization, and the presence of structural defects like dislocations or vacancies. These factors can affect the strength of interatomic bonds and influence the overall hardness of the crystal.
