Introduction: Thorium is a radioactive, solid silvery metal prior to its melting point of melting point of 3300°C. Thorium has an atomic number of 90, placing it two positions behind Uranium, on the periodic table. This is one of the two rare radioactive metals (the other being Uranium) that can be found in high quantities in the earth's crust with the majorly commercial mineral monazite, or it can be rarely found naturally in its oxidized form. Pure thorium looks silvery white and is very delicate, but will harden by the time it has reacted with the atmosphere, which takes several months. Once it starts to react, it's outermost later will undergo a form of corrosion with the atmosphere, tarnishing it black. History: The Swedish chemist, who's considered one of the founders of modern science, Jöns Jacob Berzelius, discovered thorium on an island in …show more content…
In the 19th century, famous Austrian scientist, Carl Auer, created an incandescent gas mantle using thorium oxide to coat the mantle so that it would have a light when you apply a flame/heat. You can imagine how this came into extensive demand and use during this era, when electronic lighting wasn't invented, but by the time the latter form of lighting was invented the sales for thorium oxide coated mantles declined. There was also reason to believe that there were safety issues for those involved in manufacturing the mantles due of thorium's radioactivity. However, you can still find these lanterns in camping stores. Its oxide is applied to the mixtures in heat resistant ceramics, because of its high melting point. It has more advantage, though, it has sufficient strength for materials of construction as it's resistant to abrasion, oxidation, hot water, most acids, and dilute salt solutions. Thorium is also applied as an alloying agent to improve magnesium's strength, which is used for aircraft engines.
Have you ever wondered were led lights came from..? well I Daniel Mcfarland was born in Pennsylvania on February, 27 1869 and attended Lehigh University for college from 1884-1889. I studied electrical engineering, After experimenting with different sources, I started using glow discharges to produce light. In 1986 I had devised a glow discharge lighting system, creating an extension to the Geissler tube. The lamp utilized nitrogen and carbon dioxide as the luminous gas because they emitted a soft white light. My technique was the first commercially variable light source based on gas discharge instead of incandescence, and it's considered the predecessor to contemporary neon and fluorescent lighting.
Titanium is important because it is used for a lot of stuff like airplanes,trains,tanks,helicopters,cars,and other stuff. It is also used in everyday objects.
This was a good thing so people could have a safer night light. And it was safer to carry this was made easily from a bronze or gold lamp. This was filled up with oil and another wik. This could be placed down on a flat surface or carried more easier then the stick or candle. When people heard of this. They built gas lanterns. The gas was very cheap so people just left it on. A lightning flash came but people did not know that it was electricity. So it was waiting to be used.
Gallium is the element number 31. Gallium is the one of the only metal that will be liquid in your hand. Mercury is an liquid metal element number 80 that freezes at -280 degrees fairenheight with liquid nitrogen. Mercury was a popular thing to play with but people realized that they were slowly being poisoned by it.Gallium is not known to be toxic, but it can stain your hand dark brown. cesium is another metal that will literally melt in your hand but without putting it in an ampoule, it will explode and catch on fire. Gallium tends to be the less dangerous type of liquid metal other than explosive cesium to lethal mercury. Gallium melts at a temperatue of 83.4 fairenheight. In order to buy gallium you must first order it then, they must purize
The element titanium, has the atomic number of 22 and is a member of the transition metals. It seems as a highly lustrous, silver-coloured metal. And has a name. And this metal is considered to be very durable/strong. Titanium is very common and can be found all over the world in rocks and sediments and. Like many transition metals, titanium creates oxide layers on the surface of its shell witch will react with oxygen. But however, this metal is very useful in its oxide form.
Back then, only torches, oil lamps, and candles were used for lights indoors and to aid travelers at night and in religious ceremonies.
Tritium is a form of Hydrogen, found naturally in air and water. Unlike most hydrogen, tritium has two extra neutrons in the nucleus.
Tritium (hydrogen 3) is one of the many isotopes of hydrogen. Tritium was discovered by physicists Ernest Rutherford, M. L. Oliphant, and Paul Harteck, in 1934, when they bombarded deuterium with high-energy deuterons (nuclei of deuterium atoms).
Astatine is a very rare radioactive chemical element with the chemical symbol At and atomic number 85. It occurs on Earth as the decay product of various heavier elements. All its isotopes are short-lived, with half-lives of 8.1 hours or less. Elemental astatine has never been viewed because a mass large enough to be seen by the naked eye would be immediately vaporized by its radioactive heating. The bulk properties of astatine are not known with any certainty, but they have been predicted based on its similarity to the other halogens, the lighter elements directly above it in the periodic table: fluorine, chlorine, bromine and especially iodine. It is likely to have a dark or lustrous appearance and may be a semiconductor or possibly a metal;
There are a lot of different kinds of elements in this earth. Each of which belong to a category of; non-metals, metalloids, or metals. In this paper I will be discussing about the element aluminum. Aluminum is the most abundant metal of above all the other metals but has a lot of uses. The properties of this metal are what we use for many of the things we utilize in today's world.
Molybdenum is used as glass furnace electrodes due to its high melting point. It is also used in the petroleum industry, to catalyze the removal of organic sulfur compounds in coal liquification and gas liquification processes. Molybdenum is an essential trace element for animals and plants. molybdenum can cause diarrhea, growth retardation, infertility, low birth weight, and gout; it can also affect the lungs, kidneys, and liver.
Thorium is obviously a better vitality source in correlation than uranium, and Thorium has the best advantages. We are given a more normal fuel source that creates numerous times the measure of vitality as uranium. The force of this new innovation equals that of our fossil energizes, and does not hurt our environment as the smoldering of fossil fills does. Nuclear Energies has officially ended up being a compelling distinct option for oil and coal, and thorium will lessen the dangers with the nuclear
Now-a-days magnesium is also used as a material for designing engine block. Magnesium is much lighter than cast iron and aluminum as well. But the main problem in using magnesium was that it became unstable at higher temperature. Later that problem was solved but still wide range of Al and Mg alloys are being used in the automotive industry in the current scenario. According to a study, 90% of automobiles in North American countries are using aluminum for engine block which is
These metals along with many others are used to make everthing from wire to car parts to airplane parts (Minoqua par.
Throughout history, the availability of a reliable, safe, and efficient source of energy has dictated what humans can and cannot achieve. The use of Thorium as a next generation fuel gives us the opportunity to become a wealthier and a more environmentally conscious species. Thorium also presents us with the ability to do away with virtually every other form of energy production. In a world that is completely dependent on energy, the reliability of the resource is of the utmost importance. But perhaps even more important than that is it’s safety. This is why we chose to model how the reactor handles catastrophes that could possibly put the reaction in turmoil such as earthquakes and
