Zinc is a metal that is brittle with a silver-gray color.
Zinc is believed to have been named by the alchemist Paracelsus and named after the German word “Zinke” which translates to “prong, tooth”.
Zinc was first discovered at least 3,000 years ago by Indian metallurgists in India.
Zinc was first isolated in 1746 by German chemist Andreas Marggraf. It’s important to note that Marggraf is given credit for the first isolation of zinc, but Swedish chemist Anton von Swab at the time claimed he distilled zinc from calamine in 1742, four years before Marggraf.
