Chemical Properties: Reaction with air: - When plutonium is exposed to air it begins to oxidise, it forms a yellowish-brown outer coat and begins to tarnish. Soluble in: - Hydrochloric acid Insoluble in: - Nitric acid - Concentrated hydrogen sulfide The Critical Mass: - Around 300 grams which is only about a third of that of Uranium 235 Allotopic Structures: - Plutonium exhibits six forms of crystalline structures. The only form that exists at room temperature is the alpha structure. It has the highest electrical resistivity of any metallic
Meanwhile, massive stars would turn Supergiant stars after the loss of masses due to thermonuclear fusion. At this time, massive stars with masses between Mc and MSun would become neutron stars. A neutron star usually have a small radius and consequently spin with a significant speed. It also have a strong magnetic field that emits electromagnetic wave in range of radio. Hence a neutron star is also called a pulsar.
Fission and Fusion are similar only really on the surface. That is, they both deal with atoms. That really is where the similarities end, however. Fission is concerned with the deconstruction of atoms, while Fusion involves the reconstruction of them. By using the neutrally-charged molecules called Neutrons, we blast apart an atom, splitting it into two halves and sending its own neutrons everywhere.
For example, not only are there high risks of potential meltdowns, but the nuclear waste that is is created is extremely toxic. Also, the energy source of nuclear energy is Uranium, which is a scarce resource, and its supply is estimated to last only for the next 30 to 60 years. Why are people choosing to build numerous nuclear power plants all over the world when we will eventually get stuck with them and their radioactive waste in a short period of time? The film The China Syndrome is fair to the nuclear industry because it explains the potenial dangers of a nuclear power plant realistically to the
Supernova nucleosynthesis is the theory of the production of many different chemical elements in Supernova explosions. The atomic mass of calcium is 40.078. The density of calcium is 1.55 g/L. This is the Melting point 1112 K and Boiling point 1757 K for calcium.The shell structure is 2,8,8,2.
Hydrogen bombs are more than 1000 times more powerful than the very common atomic bomb. The explosion is from nuclear fusion which is when hydrogen nuclei (plural of nucleus) are joined to form helium nuclei, releasing great destructive energy and radioactive fallout. When the nuclei combine there is a split second where there is nothing and then there is the explosion. An atomic bomb is the trigger or the smaller bomb of what sets off the hydrogen bomb. We have to be careful with the hydrogen bomb because, if used, it will cause a major catastrophe far greater than the damage done by the atomic bomb.
In 1973, the development of the JET began. The JETis a physics experiment that was theorized to be a renewable energy source by using nuclear fusion. The energy is produced by the walls of the Tokamak which absorbs the heat from the fusion of atom. After, the heat is used to produce steam and then it is converted into electricity using turbines or generators. The Joint European Torus or
Find an Atomic Shelter, fast! An Atomic Bomb is a powerful nuclear weapon used in WW2. Atomic Bombs are mostly used for destroying the enemy in one swoop, because of its massive explosive destruction. For example, the USA used two Atomic Bombs at the end of WW2, which resulted in the destruction of Hiroshima, located on the eastern end of the Chugoku-Sanji mountains. When an Atomic Bomb explodes above land it will produce a small crater, but a large amount of smoke.
The usage of plastic emits between 100-500 million tons of CO2 every year. (Staley, 2009). We could reduce carbon dioxide emissions if we stopped the production of plastic as it would be much safer for the environment. The use of plastics can have major effects on our world, and we should stop using
Throughout history, new power sources were found which eventually became a hazard rather than a salvation. Many created pollution or put workers in high risk situations. However, modern technology has made possible to ability to create power through harnessing the wind while while releasing nothing harmful into the environment. While it may be questioned if wind turbines are the best option to avoid the negative effects of other power sources, wind power in fact is a superior power source that eliminates most of the consequences of traditional power generation. Economically, the use of wind turbines has many benefits after a substantial, initial investment.
One of them is burning coal. The encyclopedia defines coal as a solid fossil fuel formed from the remains of land plants that were buried 300-400 years ago and exposed to intense heat and pressure over those millions of years. It is burned in power plants to generate electricity. Data says that 44% of the United States electricity comes from burning coal. The National Mining Association reported that in 2009, 55.4 percent of Maryland’s electricity came from it.
