Crystals of a certain mineral have a regular formation of atoms. However, crystals of the same mineral can grow differently. The presence of trace minerals, variations in heat, pressure, and the space that they have to grow in can influence the shape of a crystal. Crystalline structures demonstrate characteristic geographic variations for these reasons.
Most minerals have one crystal shape each, but that shape may be different for a different mineral. However there are a few substances which form different shapes of crystal under different conditions. This is called polymorphism, or allotropy if the substance is an element. For instance carbon can form graphite or diamond.
no or false each mineral does not have the same crystal structure
False
false
FALSE
cohesion the property of particles of the same substance to attract each other
Given that a crystal is a physical shape, Gold does naturally form crystals. And in a suitable environment, the crystals may grow. In New Zealand it has been found that the size of the gold particles in an alluvial mix, will increase the further down the stream one travels. This is because of gold particles adhering to each other.
Two dissimilar crystals join each other at the interface with lattice constants a, b multiples of each other, ma=nb. Chungchi Hsu

Crystals have regular, flat faces that form at very specific angles to each other and reflect their atomic structure. To identify what type of mineral you have, consult mindat.org, or a library, or a university earth science department, a local museum with mineral exhibits, or a local mineral collecting club.
yes. each minerals atoms are arranged in a very specific order.
There is no general shape of a mineral. Each mineral has its own shape, even though two different minerals might have the same shape. A few examples of shapes of minerals are: Rhomboid, rock, and cubic.
True !
The shape of the crystals of carbon- they lay flat, and slide against each other very easily.
Arangement of it's atoms.
Crystals are formed when the compounds in a mineral are arranged in a repeating pattern. It is a highly transparent glass mineral with a high refractive index.
Because hot water can dissolve more of the borax and it needs to be supersaturated so that when it cools it cannot hold as much borax in each molecule, so it releases some of the borax into it's natural repeating mineral shape.
No. It can vary from the visible color of the mineral and, since visible color of them ineral is not a reliable indicator of type, it is important to learn to use streak, (along with other factors), to correctly identify a mineral.
False. The term is elliptical. Eclipse is what happens when planets and moons pass in front of one another or the sun.
Depends on the substance, sometimes in crystals, sometimes random, usually a mix. The type (shape) o.f the crystals is often specific for each substance. But once in solid form, the relationship between particles remains fixed.
