Why are anions always larger than the atoms from which they are formed? Elaborate on the reasons why the electronic configurations of chromium and copper differ from the conventional configurations. Why is the three-membered ring containing nitrogen called an aziridine group so reactive? Why is bari...
Vanadium is a metallic element with the atomic number 23 and the symbol V. On the periodic table of elements, it is found in Group 5, and in Period 4 between titanium and chromium. It is referred to as a “transition metal.” Vanadium is a soft, ductile element. Described as silvery...
Chromium, also known as chrome, is a chemical element that has the symbol Cr and the atomic number 24. The first element in Group 6 of Mendeleyev’s Periodic Table and the 13th most abundant element in the Earth’s crust. Chrome is found in the mineral chromite or chrome ore. ...
Chromium (Cr), chemical element of Group 6 (VIb) of the periodic table, a hard, steel-gray metal that takes a high polish and is used in alloys to increase strength and corrosion resistance. Chromium was discovered (1797) by the French chemist Nicolas-Louis Vauquelin and isolated as the ...
while those without iron are non ferrous. Ferrous metals can be identified as magnetic, and they are most likely to rust. Steel is one of the common ferrous metals, which is made by combining iron ore and carbon. Stainless steel alloys are made by the addition of chromium to avoid rust....
cryolite, garnet, spinel and turquoise. In addition, the metal plays an important role in the formation of certain gemstones. Impurities in Al2O3, such as chromium or cobalt, cause the formations of rubies and sapphires. Pure Al2O3, known as Corundum, is one of the hardest materials known...
