What is a mineral with the same crystal system as salt?
Halite, which is the mineral name for salt, has a cubic crystal system. Therefore, another mineral with a cubic crystal system would be pyrite.
A large piece of mineral halite is broken repeatedly into perfect cubes how can this be explained?
Halite has a cubic crystal structure, which makes it naturally form into perfect cubes. When broken repeatedly along its natural cleavage planes, halite will continue to fragment into smaller cubes due to its internal molecular arrangement. This phenomenon is a result of the crystal structure of halite and its tendency to break along specific planes.
Does crystals of a mineral come always in the same size?
No, crystals of a mineral can vary in size depending on the conditions under which they formed. Factors such as temperature, pressure, and the presence of impurities can influence the size of mineral crystals.
Are sodium chloride and potassium chloride isomorphic?
Yes, sodium chloride (NaCl) and potassium chloride (KCl) are isomorphic compounds because they have the same crystal structure and similar physical properties. Both compounds belong to the same crystal system and share similar bonding characteristics due to their similar ionic sizes and charges.
Is a triclinic crystal a mineral?
Triclinic is a crystal system that describes the geometric arrangement of atoms in a mineral. Minerals can belong to different crystal systems, such as triclinic, depending on their internal structure and external crystal shape. So, a mineral can have a triclinic crystal structure, but triclinic itself is not a mineral.
