Today's element is cobalt, lovely cobalt this element is known by the symbol, co , and the atomic number 27 as you can see in the image above, cobalt looks much like its sister transition metals, being silvery-grey, shiny and solid at room temperature its name comes from the german, kobold ore, for goblin ore, because it.
We've used it for millennia, even before the common era, but it didn't get proper credit until the 18th century with its 27 protons, cobalt is sandwiched between iron and nickel in the middle portion of the periodic table with the other transition metals, which bridge the main group elements located on either. Atomic number (number of protons in the nucleus): 27 atomic symbol (on the periodic table of elements): co atomic weight (average mass of the ancient origins aside, cobalt itself was not discovered until the 1730s — and even then, it was years before the scientific community agreed that this new.
