Lol funny you ask im doing a project on Cobalt in school! Lol oka in room temperature cobalt is a solid. What is the periodic element cobalt's state of matter? Please supply the exact melting point (Kelvin) of Cobalt I am doing a science project and I was wondering how many prontons cobalt has, how many electrons cobalt has, and how many neutrions cobalt has. What is cobalt state of matter when it is a liquid It wasnt invented but it was discovered in 1735 by george brant in stockholm swedan, but it was named after German miners. Cobalt is also present in meteorites.Ĭobalt is used for several things such as batteries, glassware and more. Catalysts are substances that increase the speed of chemical reaction without being consumed by the reaction. Some other uses include dental and surgical applications, Catalysts, and Cobalt boats. Cobalt occurs in the minerals Cobaltite, Smaltite, and Erythirite and is associated with Nickel, Silver, Lead, Copper, and Iron ores. It is also used in cobalt magnets, MRI machines, electronic devices, and speakers with Aluminum, Nickel, and Iron. With those same elements, Cobalt can withstand high temperatures used in gas turbines and jet engines. Carbon and Tungsten, or Chromium and Iron, mixed with Cobalt can formulate hard alloys for drill bits and cutting tools. With Aluminum and Nickel, it is used in magnets. When mixed with Iron, Cobalt can produce high temperature steel. Cobalt can make various alloys with other metals. Cobalt Is a very useful radioactive isotope. Only some food-processing plants use radiation from Co 60 to kill bacteria in foods. A gamma ray is a high energy electromagnetic radiation given off by some nuclei. The element is also a powerful gamma ray emitter used for radio therapy, leak detection in pipes, and irradiating food to kill bacteria. Blue is the most well known shade, but pink and green are also present in glass coloring. Cobalt reacts over time with dilute acids and has remarkable magnetic properties. It is a hard, ductile, lustrous bluish-grey metal and it's surfaces are stable in air. The origin of the name comes from the German word kobald meaning goblin or evil spirit. First, it has been used for distinctive and attractive color to glass objects. Relative atomic mass: 58.933 194 (4) Cobalt was discovered by Georg Brandt (DE) in 1739.
George Brandt discovered Cobalt in Sweden in 1735Ĭobalt has many uses for its compounds. I just know that it was first discovered in Sweden in 1735-39 on the setup of nuetrons, protons and electrons in an atom of an element?ĭOES ANYONE KNOW THE NUMBER OF ELECTRONS IN COBALT FOR MY SON'S PROJECT?Ģ7 electrons, 9 valence electrons if you want to know.
That's way wrong its 27 protons and electrons and 32 neutrons Back to key information about the element Name:
