In this paper I am going to be talking about the chemistry of gallium, where you can find it, how it is used, the dangers, history behind gallium, how it is made, and characteristics of gallium.  Gallium is a metal with special properties, different compounds, and is used in some things that you might not have even realized.  Gallium is an interesting metal that has a lot of different elements.  Gallium is very cool and a very interesting metal.   In this paragraph, I am going to talk about the chemistry of gallium.  In gallium the metal crystallizes in rhombic (pseudotetragonal) system, its crystal-lattice is formed by diatomic molecules (a = 2.47 A). This structure is very rare, while the Ga-2 molecules are preserved in a molten gallium.  Although this does not have much to do with the chemistry, the atomic number for gallium is 31.  The density of the solid (5.904) that is less than liquid gallium (6.095 g/cm3), that will solidify with a 3.2% increase of the volume. Ratios of maximum to minimum  electrical resistance that is in different directions the crystal is 7 for gallium; which is much more than for any other metal (antimony, 1.2; tin, 1.4; zinc, 1.04; mercury, 1.32)41.  This is the temperature dependence of the vapor pressure of gallium, the pressure is expressed by equations 101.432: or log P atm = -14900T – 0.515 log T+7.34Or log Patm = 8,540- 1200T-0.844 log TLarge numbers of characteristic line lines, the stronger ones are the following: 4172.056, 4032.982, 2943.637, and 2874.244 A. The next thing is going to be on where gallium can be found.  Gallium is something that you cannot’ dig up like a rock or gold.  You can’t go out searching for it in the jungle or in a mine because gallium does not occur naturally.  Although you may not be able to find it, it is in Earth’s crust and can also be found in coal, diaspore, and germantine.  It is also found in very small amounts in your body. We are going to talk about the uses of gallium and how it is used.  Gallium is used in many different things like thermometers.  Human’s have a little bit of gallium in their body! This soft metal can replace mercury in thermometer it makes it non-toxic.  Gallium is sometimes used in the making of mirrors which gives it a very brilliant reflection.  Gallium arsenide, GaAs, can be a promising material in the production of most solar batteries and silicon.  Gallium in the “cold shouldering” of metallic and also ceramic articles.  It is also used in vacuum devices, diffusion of pumps, and lubricating moving parts of electrical vacuum devices.   Just like any other metal there are dangers or risks of using the materials.  Now we are looking at the dangers and risks in using gallium.  If you ingest large amounts of gallium there are some very concerning health risks such as throat irritation, difficulty breathing, as well as chest pains, and the fumes can cause incredibly serious health conditions such as pulmonary edema and also partial paralysis.  This substance can also cause fires so it is recommended to have a fire extinguisher on hand.  Gallium is nontoxic other than when ingested.   Now we are going to talk about the history behind gallium who found it, when it was discovered, and ect… .  The discoverer of gallium is Paul-Emile Lecoq de boisbaudran in 1875.  It was found in Paris on the continent of Europe.  De Boisbaudran had extracted gallium in first instance zinc blende ore.  The origin for gallium came from a latin word ‘gallia’, it means France.Dmitri Mendeleev had predicted the properties, he is a Russian chemist.   Let’s talk about how gallium is created or produced.  Small amounts of gallium are produced as by-products of zinc.  They  crush ore then wash it with a hot solution of sodium hydroxide (NaO8).  It then converts to alumina to sodium aluminate.  The gallium cycle will continue in China, now they produce 70% of the worlds gallium.  It is also produced in ukraine and Kazakhstan. THe last thing I am going to talk about are the characteristics of gallium
