Although all minerals have an orderly internal arrangement of atoms crystalline structuremost mineral samples do not visibly demonstrate their crystal form why?
Minerals can form in clumps, as a druse over existing surfaces, and a variety of other ways, all under different conditions. Quick cooling igneous rocks are composed of minerals, but the crystalline structure is too small to see with the naked eye. Euhedral (perfectly formed, visible crystals demonstrating the typical crystal form) crystals in most minerals are a rare find for the average collector.
Is ruby a type of crystal?
A ruby is a crystal form of the mineral corundum.
What is the difference between crystal form and cleavage?
Crystal form refers to the geometric shape the mineral acquires upon solidification. Cleavage is a mineral property that describes the tendency of a crystal to break along planes of weakness.
What is a physical characteristic determined by the arrangement of the atoms within the mineral?
A mineral crystal. Minerals form a crystalline structure.
Which property of a mineral most directly results from the internal arrangements of its atoms?
crystal shape

A ruby is a crystal form of the mineral corundum.
Is pyrite a crystal?
Pyrite is a mineral that can form crystals.
Is a crystal an igneous rock?
No. A crystal is the solid form of a mineral. Mineral crystals are present in nearly every rock, regardless of type.

Crystal form refers to the geometric shape the mineral acquires upon solidification. Cleavage is a mineral property that describes the tendency of a crystal to break along planes of weakness.

A mineral crystal. Minerals form a crystalline structure.
Does a mineral have crystal form but no cleavage?
All minerals have a crystal form, but not all have cleavage.
What determines the size of the crystal that form in a sample of granite?
Crystal size in igneous rock is predominately a factor of time spent in cooling from lava or magma. Samples with relatively large crystals are the result of the magma having spent a longer amount of time at ideal crystal forming temperatures for each mineral present.
Which property of a mineral most directly results from the internal arrangements of its atoms?
crystal shape
Which substance would form a mineral crystal sugar or salt?
salt
What is the shape a mineral forms in nature?
Minerals form crystal structures.
What is a tabular crystal habit?
A tabular crystal habit refers to the appearance of a mineral crystal as a somewhat flat, tablet shaped form.
