The Elements of Life:

Chromium Chromium is a silver, lustrous, hard transition metal in Group 6 on the periodic table; with an atomic number of 24, an atomic weight of 51.9961, and an electron configuration of [Ar] 3d5 4s1. It has several applications in metals, chemicals, and refractories. It is one of the most significant strategic and vital commodities for the modern world. The addition of chromium to iron, steel, and nonferrous alloys improves hardenability and resistance to corrosion and oxidation. Two of the most important uses of chromium are the production of stainless steel and nonferrous alloys.  History:  Chromium was first discovered in...

What is Gold:  Gold is a yellow to a pale whitish-yellow metal with the formula Au. It has a metallic luster, a hardness of 2.5 to 3, and an atomic number of 79 on the periodic table.  The majority of gold produced nowadays is used in the production of jewelry. However, gold emerged as an essential industrial metal in the late twentieth century because of its better electrical conductivity and corrosion resistance. Gold serves vital tasks in computers, communications equipment, spacecraft, jet aircraft engines, and various other items. Although gold is essential in industry and the arts, it also has...
