What is the hardest element on earth?
The outermost shell of each carbon atom has four electrons. In diamond, these electrons are shared with four other carbon atoms to form very strong chemical bonds resulting in an extremely rigid tetrahedral crystal. It is this simple, tightly-bonded arrangement that makes diamond one of the hardest substances on Earth.

In this process, barite is crushed and mixed with water and other materials. It is then pumped into the drill hole. The weight of this mixture counteracts the force of the oil and gas when it is released from the ground.
Is barite used in drilling?
Currently, the majority of barite consumption in the United States is for this drilling application. However, the consumption in drilling “mud” fluctuates from year to year, as it is dependent on the amount of exploration drilling for oil and gas, which in turn depends on oil and gas prices. Beyond this, barite is used as an additive ...

Beryllium is a hard, grayish metal naturally found in mineral rocks, coal, soil, and volcanic dust . The commercial use of beryllium requires the use of appropriate dust control equipment and industrial controls at all times because of the toxicity of inhaled beryllium-containing dusts that can cause a chronic life-threatening allergic disease in some people called berylliosis.
What is the densest element in the universe?
If we include man made elements, the densest so far is Hassium . Hassium is a chemical element with symbol Hs and atomic number 108. It is a synthetic element (first synthesised at Hasse in Germany) and radioactive. The most stable known isotope, 269Hs, has a half-life of approximately 9.7 seconds. It has an estimated density of 40.7 x 103 kg/m3. The density of Hassium results from its high atomic weight and from the significant decrease in ionic radii of the elements in the lanthanide series, known as lanthanide and actinide contraction.

What is the atomic number density?
Atomic Number Density. The atomic number density (N; atoms/cm 3 ), which is associated with atomic radii, is the number of atoms of a given type per unit volume (V; cm 3) of the material. The atomic number density (N; atoms/cm 3) of a pure material having atomic or molecular weight (M; grams/mol) and the material density (⍴; gram/cm 3) is easily computed from the following equation using Avogadro’s number ( NA = 6.022×1023 atoms or molecules per mole):
What is the density of a substance?
Since the density (ρ) of a substance is the total mass (m) of that substance divided by the total volume (V) occupied by that substance, it is obvious, the density of a substance strongly depends on its atomic mass and also on the atomic number density (N; atoms/cm 3 ),

What is Barite?
Barite is a mineral composed of barium sulfate (BaSO 4 ). It receives its name from the Greek word "barys" which means "heavy." This name is in response to barite's high specific gravity of 4.5, which is exceptional for a nonmetallic mineral. The high specific gravity of barite makes it suitable for a wide range of industrial, medical, and manufacturing uses. Barite also serves as the principal ore of barium.
How to identify barite?
Students should be able to easily identify barite using the "heft test" (placing Specimen "A" in their right hand and Specimen "B" in their left hand and "hefting" the specimens to determine which one is heaviest). Students in third or fourth grade are capable of using the heft test to identify barite.
Why do you need an x-ray of your throat after a barium swallow?
An x-ray of the throat taken immediately after the "barium swallow" will image the soft tissue of the esophagus (which is usually transparent to x-rays) because the barium is opaque to x-rays and blocks their passage. A "barium enema" can be used in a similar way to image the shape of the colon.
Where does barite occur?
Barite Occurrence. Barite often occurs as concretions and void-filling crystals in sediments and sedimentary rocks. It is especially common as concretions and vein fillings in limestone and dolostone. Where these carbonate rock units have been heavily weathered, large accumulations of barite are sometimes found at the soil-bedrock contact.
Is barite a nonmetallic mineral?
Barite is generally easy to identify. It is one of just a few nonmetallic minerals with a specific gravity of four or higher. Combine that with its low Mohs hardness (2.5 to 3.5) and its three directions of right-angle cleavage, and the mineral can usually be reliably identified with just three observations.
What is barium dihydrate?
Ans. Barium Chloride Dihydrate is an optimal source of barium for high purity constructions and methods in the optical, electronic, and pharmaceutical industries.
