Your Questions About How To Discover New Elements

Charles asks…

Do synthetic elements exist in other parts of the universe?

I know that these elements cannot be found on earth and are said to exist nowhere. But does that mean they are not found anywhere in this super huge and mysterious universe?

New Niche Finder answers:

Synthetic just means that they are man-made, not naturally occuring.
Theoretically they could exist in parts of the universe we haven’t discovered yet, but it is highly unlikely.

Sandra asks…

why was the discovery of oxygen so important?

Joseph priestly discovered the element Oxygen. why is this an important discovery?

New Niche Finder answers:

90% of our NUTRITIONAL ENERGY comes from oxygen and ONLY 10% is derived from ingested food? Basically, your body starves without oxygen. It is one of the most basic needs.

Donald asks…

Do humans need any rare earth elements in their bodies for proper functioning?

Do humans need any rare earth elements in their bodies for proper functioning?

New Niche Finder answers:

Probably not. No biological molecule yet discovered contains a rare earth element, and it seems that the body lacks the means to deal with rare earth metal ions, which are slightly toxic, tend to build up in the bones, and are excreted extremely slowly.

Mary asks…

How was the element Manganese discovered ?

Does anyone know how the element Manganese was discovered ?
im doing an element project for school but i can’t find how it was discovered.

New Niche Finder answers:

Proposed to be an element by Carl Wilhelm Scheele in 1774, manganese was discovered by Johan Gottlieb Gahn, a Swedish chemist, by heating the mineral pyrolusite (MnO2) in the presence of charcoal later that year. Today, most manganese is still obtained from pyrolusite, although it is usually burned in a furnace with powdered aluminum or is treated with sulfuric acid (H2SO4) to form manganese sulfate (MnSO4), which is then electrolyzed.

John asks…

i have to write a paper for chemistry class, its on the element silicon. Anyone know any good web sites?

Its supposed to be on the element, its compounds, what its used for in everyday life and diffrent things like that. Any help would be greatly appreciated seeing as how i have yet to start and it is due tomorrow. Thanks.

Silicon is one of man’s most useful elements. In the form of sand and clay it is used to make concrete and brick; it is a useful refractory material for high-temperature work, and in the form of silicates it is used in making enamels, pottery, etc. Silica, as sand, is a principal ingredient of glass, one of the most inexpensive of materials with excellent mechanical, optical, thermal and electrical properties. Hyperpure silicon can be doped with boron, gallium, phosphorus, or arsenic to produce silicon for use in transistors, solar cells, rectifiers, and other solid-state devices, which are used extensively in the electronics and space-age industries.

Though silicon was originally discovered in 1810 and thought to be a compound silicon was discovered as an element in 1823 by Jons Berzelius. In 1824 Berzelius prepared amorphous silicon by the same general method and purified the product by removing the fluosilicates by repeated washings. Deville in 1854 first prepared crystalline silicon, the second allotropic form of the element. Davy in1800 thought silica to be a compound and not an element; later in 1811, Gay Lussac and Thenard probably prepared impure amorphous silicon by heating potassium with silicon tetrafluoride.

Silicon is a metalloid at room temperature with an atomic number of 14, 14 electrons, 14 neutrons, and an average atomic mass of 28.0855. In its pure form,silicon melts at 2,570 degrees, and boils at 4,271 degrees Fahrenheit. This element belongs to the metalloid family, the 14th family on the periodic table of elements. This element is a solid metalloid at room temperature and turns to liquid at 2,570 degrees. Silicon is prepared as a brown amorphous powder or as gray-black crystals. Crystalline silicon has a metallic luster and grayish color. It is hard, non-magnetic, and most acids do not effect it, but it does dissolve in hydrofluoric acid, forming the gas, silicon tetrafluoride, SiF 4. At ordinary temperatures silicon is impervious to air, but at high temperatures it reacts with oxygen, forming a layer of silica that does not react further. At high temperatures it also reacts with nitrogen and chlorine to form silicon nitride and silicon chloride, respectively. Elemental silicon transmits more than 95% of all wavelengths of infrared, from 1.3 to 6.y micro-m.

Silicon is present in the soil and makes up about 25.7% of the earth’s crust. Silicon also promotes firmness and strength in human tissues. It is part of the arteries, tendons, skin, connective tissue, and eyes. This mineral is also present with the chondroitin sulfates of cartilage, and it works with calcium to help restore bones. Silicon is also thought to radiate or transmit energy in its crystalline structure, as in quartz crystal. It is thought by some to be able to deeply penetrate the tissues and help to clear stored toxins. Research shows silicon is important to plant and animal life. Results of studies on animals suggest that silicon may be essential to humans. This mineral is able to form long molecules, much the same as is carbon, and gives these complex configurations some durability and strength. It represents about 0.05 percent of our body weight.

Silicon is present in the sun and stars and is the second most abundant element, being exceeded only by oxygen. Silicon is not found free in nature, but occurs chiefly as the oxide and as silicates. Sand, quartz, rock crystal, amethyst, agate, flint, jasper, and opal are some of the forms in which the oxide appears. Granite, hornblende, asbestos, feldspar, clay, mica, etc. Are but a few of the numerous silicate minerals. Silicon is prepared commercially by heating silica and carbon in an electric furnace, using carbon electrodes. Several other methods can be used for preparing the element. Amorphous silicon can be prepared as a brown powder, which can be easily melted or vaporized. The Czochralski process is commonly used to produce single crystals of silicon used for solid-state or semiconductor devices. Hyperpure silicon can be prepared by the thermal decomposition of ultra-pure trichlorosilane in a hydrogen atmosphere, and by a vacuum float zone process.
