What Is Thorium?
My element is Thorium (Th). The atomic mass number is 232.038.06 and the atomic number is 90. The melting point is 202./8 K. Thorium belongs to a group called Actinide series.Thorium is a solid at room temperature. Thorium melting point is 2028K, boiling point 5061K, and there is no freezing point. Thorium was found in 1815 by a guy named Jons Jakob Berzelius. It is used alloying agent to improve Magnesium's strength at high temperature. Thorium is also used to coat Tungsten filaments used in electronic devices, such as television. It is used to make glass with a high index of refraction that is used to make in high quality camera lenses. Thorium oxide is used as an industrial catalyst. It is also used for a source of nuclear power. It can

    Gallium Research Paper

    Gallium has a soft texture; you can even cut gallium with a knife. It is silver in color and is also used in semiconductors and light diodes. Gallium would melt in a human’s hand. Now, gallium can be cooled also without turning into solid and that gives it this special property. The melting point of it is at 29.7 degrees Celsius, whereas its boiling point is at 2204. It is highly reactive with non-metals. It highly reacts with aids and alkalis. Gallium is a conductor which means that it is used in the production of many items, for example like smartphones, technological devices and is also responsible for the Wi-Fi everyone can’t live without! It is also used in LEDs and solar panels as well. The thing is that Gallium immediately converts the electricity into light. Another interesting thing is that Medical centers use gallium for the thermometers because Gallium is not toxic. One more thing to know about this important element is that it is obtained by electrolysis. Some more interesting facts about Gallium is that it gets used in Neutrino Observatory in Italy where they use it to study solar neutrinos. It is also used in the production of Lasers. Gallium is non-toxic…

    Boron Project

    My element name is Boron. My slogan is my symbol is B! I 'm right at the top of Group IIIB! When the first time seen my element is in the PT. boron symbol is B and is in Group IIIB. Two of them are having B. It looks very simple. I think that is very fun idea, so I just use this for my slogan. Boron is a chemical element with chemical symbol B and atomic number 5. It is in period 2, Group 13 element that has properties which are nonmetals. The name boron comes from the Arabic and Persian words for borax. Boron was discovered by Sir Humphrey Davy, Joseph-Louis Gay-Lussac, and L.J. Thénard at 1808 in England, France. Boron exists in the earth 's crust to the extent of only about 10 ppm. Boron is solid and black. It is very hard and in extremely pure form is nearly as hard as diamond, but much too brittle for practical use. The atomic mass is 10.811g. Density is 2.34g/cm^3. Melting point is 3769︒F and boiling point is 7101︒F.Siilicon is the closely related elements with boron. Boron is used in pyrotechnics and flares to produce a green color. Boron has also been used in some rockets as an ignition source. Boron is used to control nuclear reactions. It is an excellent neutron absorber. Alloyed with steel or reacted with carbon, titanium or zirconium, it is used in control rods for nuclear reactors Boron is an essential nutrient for all green plants…

    Gold and High Melting Point

    I am usually found around the middle part of the periodic table. I am found below Silver and between the two elements, Platinum and Mercury. I am placed in the d-block element section of the periodic table. My atomic number is 79 and the mass of my most stable isotope and is basically my atomic mass is 196.967. The type of phase that I am at room temperature is solid. I am the most malleable and ductile of all metals. If you take one gram of me and start beating me repeatedly with a hammer of some sort, you will soon end up with a sheet of one square meter. If you take one ounce of me, you will end up with 300 square feet.…
