One of the hardest substances on earth, only a diamond is hard enough to cut other diamonds. It is possible only because the hardness of diamond varies widely according to the direction in which one is trying to cut or grind. Therefore a harder diamond is used to cut one that is slightly softer (due to impurities).

List the five characteristic a substance must have to be a mineral explain why coal and a glass marble are not minerals?
To be a mineral, a substance must be naturally occurring, inorganic, solid, have a definite chemical composition, and have an ordered atomic structure. Coal is organic in origin, formed from the remains of plants; therefore, it is not a mineral. A glass marble is man-made and lacks a naturally occurring origin, so it also does not meet the criteria to be considered a mineral.
What substances are in magnesium?
Magnesium consists of magnesium atoms, which are metallic elements found in group 2 (or 2A) of the periodic table. It is a naturally occurring element and is commonly found in minerals like dolomite and magnesite.
What are some examples of naturally occurring social systems?
wolf packs and bee colonies because they know their job, therefore it is naturally occurring and the animals that work together create the social aspect.YOUR WELCOME
Is silicone made out of the element silicon?
Silicone materials are partly made of the element silicon, but most or all the silicon atoms in them are also bonded to oxygen atoms. Therefore, silicone materials do not have the chemical properties of pure elemental silicon.
Is obsidian compound an element or mixture?
Obsidian is a naturally occurring volcanic glass composed primarily of silicon dioxide, which is a compound made up of the elements silicon and oxygen. Therefore, obsidian is not an element but a mixture of elements in compound form.

When and where did salt form?
Salt (NaCl) is a naturally occurring substance (and therefore was not invented) that has been known about since prehistoric times. It has existed as a compound at least since the oceans formed, long before people arrived on the planet.
Is nitrous oxide illegal in Japan?
Nitrogen is a naturally occurring element. Oxygen is a naturally occurring element. The combination of two naturally occurring elements together in a particular way is not illegal. Therefore nitrous oxide is not illegal in Japan or anywhere eles in the known universe. The saturation of carbon dioxide in your brain, however, is dangerous to your health.
What is a mi mineraloid?
It is important to distinguish between a mineral and a mineraloid. A mineral is an inorganic, naturally occurring substance that has a characteristic chemical composition, distinctive physical properties, and solid crystalline structure (an order 3 dimensional arrangement of atoms or molecules). If it does not have this solid crystalline structure, it is not a true mineral and is therefore a "mineraloid."
What substances are in magnesium?
Magnesium consists of magnesium atoms, which are metallic elements found in group 2 (or 2A) of the periodic table. It is a naturally occurring element and is commonly found in minerals like dolomite and magnesite.
What are the Raw materials obtained after oil extraction?
raw materials are grown naturally, therefore they are obtained in civil matters. look in a chemistry book.
How are rocks minerals and elements related?
Elements are the building blocks of minerals, which are naturally occurring, inorganic solid compounds with a specific chemical composition and crystalline structure. Rocks are made up of one or more minerals, as well as sometimes organic materials or other rock fragments. Therefore, rocks are composed of minerals, which in turn are made up of elements.
Why are fossils not considered a mineral?
Minerals are solid, inorganic, naturally occurring, have a fixed chemical composition, and not finally, a perfect internal atomic structure. Fossils come from organic materials. Therefore, fossils are not considered minerals, although yes, by the time the organic material has fossilized, consists of minerals.
Is mercury a natural?
If you mean a naturally occurring element, yes. However it is reactive and therefore not usually found in the pure metal form, instead it is found in compounds as ore.
Can you describe vitamins?
Vitamins are naturally occurring compounds present in most foods. The human body cannot produce vitamins and therefore has to acquire them from external sources: diet or supplements.

Who created scandium?
Scandium (atomic number 21) is a naturally occurring element, created, therefore, by the Creator of All Things. It is an ongoing process in the nuclear fusion engines at the heart of old stars.
