He even predicted the properties of ‘eka-aluminum’ like density, atomic weight, melting point, density of oxide, formula of oxide, and nature of hydroxide. Unlike all my other integrated circuit wafers, this one is incredibly thin. Nov 30, 2013 - This Pin was discovered by Eve Sheppard. 40. The post-transition metals include some of the Boron family elements — aluminum, indium and thallium — but also tin (Sn), lead (Pb) and bismuth (Bi). 39. This property made gallium an early metal for thermometric uses. By using our website, you agree to the cookie and privacy policy of Facts Legend. Gallium dissolves in water and aqueous solutions of gallium have hydrated gallium ions. It is surprising that the properties of ‘eka-aluminum’ and gallium are more or less same. When painted on glass, gallium turns into a lustrous mirror. 53% of it came from cell phones, 27% from wireless communications, and the rest of it from consumer, automotive, fiber-optic, and military applications. Now that we learnt about the isotopes of gallium, let us now move on to gallium facts. 24. Gallium is also used in some pharmaceuticals and radiopharmaceuticals. Gallium is a liquid at 30°C, so one would expect it to become … Later that year, Lecoq de Boisbaudran obtained pure gallium through the electrolysis of gallium hydroxide in potassium hydroxide, according to the Jefferson Lab. Interesting Facts about Gallium. So, today let’s learn about gallium facts. Gallium is often found as a trace element in diaspore, sphalerite, germanite, bauxite, and coal. If it is held in a person's hand, it will melt. Gallium expands when it solidifies by 3.1%. This link take you away from the Fun Kids website. Gallium reacts with chalcogens (oxygen family elements) at high temperatures only. Physical Science. Blue and violet optoelectronic devices use indium gallium nitride and gallium nitride semiconductors. 44. Interesting Facts about Gallium Gallium is the 31st cell element in the Periodic System Table predicted by Russian chemist and inventor Dimitri Mendeev, who created the periodic table of elements. Electron configuration and elemental properties of gallium. 33. Get facts about the element gallium. 23. It is a post-transition metal meaning it is located between transition metals and metalloids or non-metals. Tellurium is critical to efficient, thin-film photovoltaic cells that produce electricity from sunlight. It belongs to period 4 and p-block. Gallium: The 2014 Nobel Prize in Physics was awarded to the discoverers of blue LED lights made from gallium. It belongs to group 13 or boron group. In some ways, however, it is very un-metal-like. Gallium is not a very reactive metal. 8. Gallium is used to make amazing mirrors. He named gallium as ‘eka-aluminum’ on the basis of the periodic table. For example, the bauxite ore can u… At high temperatures, it has a low vapor pressure. It also expands when it freezes so it cannot be stored in glass containers. Gallium has two stable isotopes that are found in nature: Gallium-69 and Gallium-71. He didn’t name the element gallium but named it as gallia (In Latin, Gallia means Gaul). Please refresh the page and try again. The atomic number of gallium is 31. Then if you set it back down, it would solidify again. Interesting Gallium Facts: Paul Emile Lecoq de Boisbaudran discovered gallium in 1875 using a spectroscope. The electronegativity of gallium is 1.81 on Pauling scale. Liquid gallium can be quite difficult to work with, however, as it clings to glass, skin and most other materials (except graphite, quartz and Teflon). Gallium has a very large liquid temperature range which is why its used in several high thermometers Gallium dissolves in strong acids and alkalis. Crystal Structure: Orthorhombic ; Uses: Gallium wets glass or porcelain and forms a brilliant mirror when it is painted on glass. 5. Gallium (Ga) 5. It makes a stain on your hand when put on your hand. Before we begin our gallium facts, let us take a look at the isotopes of gallium. 14. The boiling point of gallium is 2673 K (2400 °C, 4352 °F). He later isolated the metal by electrolysis. 99.99% pure gallium is used in semiconductor industry. Approximately 95 percent of gallium consumption is in the electronics industry, according to. It does not dissolve in nitric acid because of the protective film of gallium oxide that is formed over the surface by the action of the acid. Lecoq de Boisbaudran wondered if element 31 might be found in zinc ores. Another unusual property is that gallium can be supercooled rather easily. 18. 25. Are you ready? New York, Etched gallium arsenide wafer. So, it is important not to store liquid gallium in metal or glass containers because the containers would break when gallium changes state. 2. . Gallium is a metal and it’s really special because it it melts at 29.76°C (thats the same temperature as a really hot day in the summer) and boils at over 2000°C which is about 7 times hotter than your oven! The atomic number of gallium is 31. 22. Gallium arsenide makes up nearly 95% of the world’s gallium consumption every year. Gallium has been used in nuclear bombs to stabilize the crystal structure. Gallium nitrate and gallium citrate are used as radiopharmaceutical agents in nuclear medicine imaging called gallium scan. It is one of four metals (including mercury, rubidium and caesium) that are liquid at or near room temperature. 43. 26. 27. It has an atomic radius of 135 picometers. It belongs to group 13 or boron group.
