Recommended: Dmitri mendeleev contribution in science

In chemistry, out of all the elements on the periodic table, there are a few that stand out because of certain characteristics, Gallium is one of these elements. On the periodic table, Gallium has the symbol Ga and atomic number 31. Gallium is a metal that has uses in such things as, medical, industrial, and everyday life. Gallium is a metal that was discovered in 1875 by Paul Emile Lecoq De Boisbaudren and is a “byproduct of the manufacture of aluminum” (“Gallium.” Web). Gallium has a low melting point of 29.76°c which is just slightly above room temperature. But even with an unusually low melting temperature, gallium has a very high boiling point of 2204°c. “Gallium expands by 3.1% when it solidifies” (“Gallium.” Avalon). Gallium was an element that was predicted by Dmitri Mendeleev and it “Validated his periodic table of elements” (“Gallium.” Avalon). When in solid form, Gallium has a Silver and reflective appearance. The picture above shows Gallium in the solid and liquid form. This picture also shows the atomic number for Gallium, which is 31. It also shows the symbol ...

  • History of the Element Boron

    625 Words  | 2 Pages

    Boron is one of the many elements on the periodic table. Its atomic number is five and its symbol is the letter B. Boron’s atomic weight is 10.811. It is a solid at room temperature. The group number for Boron is 13 and the periodic number for Boron is 2. It is also in the p block. Its element category is a metalloid. Boron came from the Arabic word Buraq and the Persian word Burah, which are both meanings for the material called “Borax.” Boron is a tough element – very hard, and very resistant to heat. In its crystalline form it is the second hardest of all the elements on the mohs scale – only carbon (diamond) is harder. Only 11 elements have higher melting points than boron: these are C, W, Re, Os, Ta, Mo, Nb, Ir, Ru, Hf, and Tc. Boron was discovered by Joseph Louis Gay-Lussac and Louis Jacques Thenard on June 30th on 1808. This element has contributed to chemistry enormously over the years. This is the history of Boron and how it has affected chemistry.

    At 20 degrees celsius it is proven that Samarium has stayed a solid. During further testing chemist found 62 protons 88 neutrons and 62 electrons in the element. Based on the evidence founded by the chemist the Element is an Isotope because the protons and electrons are the same. Samarium Is a small light and frizzle item that could be mistaken with brass due to its color and structure.

  • Gallium Research Paper

    While gallium does not have a natural function in biology it does have roles in biomedicine. Gallium ions interact with processes in the body similar to iron(III) (Dynamic Periodic Table). Since these processes include inflammation, a marker for many disease states, several gallium salts are used in pharmaceuticals and radiopharmaceuticals in medicine (Dynamic Periodic Table). When gallium ions are mistakenly taken up in place of iron(III) by bacteria, the ions interfere with respiration and the bacteria dies (Dynamic Periodic Table). The reasons for this is because iron(III) is redox-active which allows the transfer of electrons during respiration whereas gallium is redox-inactive and does not allow for the transfer of electrons during respiration (Dynamic Periodic Table). Another application is gallium nitrate. Gallium nitrate is used as a intravenous pharmaceutical to treat hypercalcemia associated with tumor metastasis to bones (Dynamic Periodic

    In the periodic table Beryllium is the first element in the second group. The chemical symbol is Be. Beryllium is an Alkaline earth-metal which means that Beryllium is really reactive but not as reactive as the Alkaline metals which is the first group. Beryllium has a melting point of 1287 degrees celsius and a boiling point of 2468 degrees celsius. In 1797 Nicholas Louis Vauquelin founded Beryllium. The density of Beryllium is 1.85. Beryllium is between Lithium and Boron. Beryllium is a shiny,steel gray,and metal that can be used for missiles, high-speed aircraft,spacecraft, and communication satellites. When used as an alloying agent in Beryllium copper beryllium can be used as a spring or a spot-welding electrode and non-sparking tool.

  • What Is Bismuth?

    Although many of Bismuth’s applications to modern life relate to more recent technology, surprisingly, experimentation with Bismuth dates back to 15th-century alchemy. At the time, most scientists believed Bismuth was a an isotope of lead, rather than a unique element, as a result of the elements’ similar appearances and densities. When the French chemist Claude-François Geoffroy published his experiments, proving the unique identity of Bismuth, in 1753, the element finally received a home on the periodic table. With an atomic mass of 208.980 amu, the most common forms of Bismuth are 20883Bi and 20983Bi. Bismuth is a solid at 0° C, with a melting point of 271° C and a boiling point of 1564° C. Just
