Hafnium was discovered in 1923 by Dirk Coster and George Charles von Hevesy in Copenhagen, Denmark. They found it in zirconium ores and named it after the Latin name for Copenhagen, Hafnia.
Zirconium is named after the mineral zircon, where it was first discovered. The name is derived from the Persian word "zargun," meaning "gold-colored." Despite the name, zirconium is a silver-gray metal.
The mass number of zirconium 98 is 98. This number represents the total number of protons and neutrons in the nucleus of an atom of zirconium. Zirconium has 40 protons, so the remaining 58 particles are neutrons.
The element zirconium was named after the mineral zircon, where it was first discovered. Zirconium is commonly found in zircon minerals and is often associated with other elements like silicon, hafnium, and thorium. The name zircon itself is derived from the Arabic word "zargun," meaning "gold-colored."
Zirconium tetrachloride can be prepared from zirconium carbide by reacting with chlorine gas at high temperatures. The reaction equation is: ZrC + 4Cl2 -> ZrCl4 + C.

Zirconium is the name of a chemical element. Zirconium has atomic number 40, which by definition means that is has forty protons in its atomic nucleus.
Zirconium is named after the mineral zircon, where it was first discovered. The name is derived from the Persian word "zargun," meaning "gold-colored." Despite the name, zirconium is a silver-gray metal.
The process used for the purification of zirconium is called the Kroll process. This process involves converting zirconium tetrachloride into metallic zirconium through a reduction process using magnesium.
