Galena, i thinx
When a mineral breaks into cubes upon being struck with a rock hammer, the property being measured is its cleavage. Cleavage refers to the way a mineral breaks along specific planes of weakness, producing flat surfaces. In this case, the cubic breakage indicates that the mineral has a cubic cleavage, reflecting its internal crystalline structure.

The mineral galena breaks into tiny cubes due to its perfect cleavage, which is a property related to its crystalline structure. Galena has a cubic crystal system and a high degree of symmetry, allowing it to cleave smoothly along specific planes. This results in the formation of small, cube-like fragments when the mineral is broken.
Quartz is a mineral that cannot split easily along a certain direction because it lacks cleavage. Instead, quartz breaks in a conchoidal fracture, producing curved, shell-like surfaces.
Mica is a mineral with crystals that break easily into two flat sheets, known for its shiny appearance and flexibility.
The property that causes the mineral galena to break into tiny cubes is its perfect cubic cleavage. This characteristic results from the arrangement of lead and sulfur atoms in its crystal lattice, which allows the mineral to cleave smoothly along specific planes. When struck or subjected to stress, galena breaks along these planes, producing small, cube-shaped fragments.
Halite forms cubes. It has excellent cleavage in 3 directions, which is why it breaks into cubes.
Galena breaks into tiny cubes due to its crystal structure, which is cubic. When it fractures, it tends to break along its natural cleavage planes, resulting in the formation of small cube-shaped fragments.
It wil break & produce fragments of d same shape as d parent material bcos it broke on a flat surface
A mineral that breaks into jagged pieces exhibits fracture.
Halite, or rock salt, breaks into little cubes due to its crystalline structure, which is formed by the arrangement of sodium and chloride ions in a repeating, orderly pattern. This symmetrical lattice structure creates planes of weakness along which the mineral can easily cleave or break. When force is applied, halite fractures along these planes, resulting in the characteristic cubic shapes. This property is typical of many minerals with similar crystalline forms.
When a mineral breaks along a weakly-bonded plane, it is called cleavage. Cleavage is a property that describes how a mineral breaks along its crystal structure.
