Salt and limestone
During mineral growth, atoms accumulate on existing surfaces or boundaries within the mineral structure. This process contributes to the enlargement of mineral crystals and the formation of new mineral layers.
Cleavage is a physical characteristic determined by the arrangement of atoms within a mineral. Cleavage describes how a mineral breaks along planes of weakness due to its atomic structure, creating smooth, flat surfaces. The number and orientation of these planes are unique to each mineral.
The shape of a mineral depends on the chemical structure that the bonds form between atoms in the mineral. A cubic mineral (such as pyrite) has a chemical structure that, as bonds are made, a cubic shape is formed.
The mineral example you're referring to is olivine. Olivine has a simple structure consisting of single silica tetrahedra linked by atoms of magnesium and iron.
crystal shape
Amber is not a mineral, because it has an organic origin and amorphous structure (no orderly internal arrangement of atoms).
Diamonds are the hardest mineral because of their unique crystal structure, which consists of carbon atoms arranged in a strong and compact tetrahedral pattern. This structure allows diamonds to resist scratching and maintain their shape even under extreme pressure, making them the hardest known natural material.
The internal arrangement of atoms.
crystalline structure
Arrangement of atoms and ions within the mineral's crystal lattice structure, which is determined by the mineral's chemical composition and bonding properties. This unique arrangement leads to the formation of distinct crystal shapes that can vary depending on external factors like temperature and pressure during the mineral's formation.
atomic packing arrangements of ions, atoms etc. A crystal structure is a characteristic of a mineral.
new mineral with a different crystalline structure.
During mineral growth, atoms accumulate on existing surfaces or boundaries within the mineral structure. This process contributes to the enlargement of mineral crystals and the formation of new mineral layers.
Diamonds are hard because of their unique atomic structure, which consists of carbon atoms bonded in a strong, three-dimensional network. This network of bonds makes diamonds extremely resistant to scratching and breaking, giving them their renowned hardness.
It is a silicate mineral ex: crystals
Cleavage is a physical characteristic determined by the arrangement of atoms within a mineral. Cleavage describes how a mineral breaks along planes of weakness due to its atomic structure, creating smooth, flat surfaces. The number and orientation of these planes are unique to each mineral.
Diamond is a mineral that does not contain oxygen. It is composed of pure carbon atoms arranged in a crystal lattice structure.
