Where was chlorine found first?
Identified as an element by Sir Humphry Davy in 1810. Occurrence: Found in nature dissolved in salts in seawater and in the deposits of salt mines. Today, most chlorine is produced through the electrolysis of aqueous sodium chloride.

Where and how was chlorine obtained?
Chlorine is obtained by the electrolysis of sodium chloride solutions. Along with sodium, chlorine is abundant in the oceans. Chlorine is present in small amounts in many minerals. The most common chlorine-bearing mineral is, of course, halite (sodium chloride).
When was rhodium discovered?

Why is rhodium so rare?
Rhodium (Rh) is a relatively unknown precious metal, possibly due to its global demand being concentrated in auto-catalysts, where it is used in smaller quantities alongside sister PGMs palladium and platinum. It is considered the rarest and most valuable precious metal in the world — far more so than gold or platinum.
Is chlorine considered to be a compound or an element?
Chlorine is a chemical element with the symbol Cl and atomic number 17. The second-lightest of the halogens, it appears between fluorine and bromine in the periodic table and its properties are mostly intermediate between them. Chlorine is a yellow-green gas at room temperature.
Who discovered chlorine element?
Swedish chemist Carl Wilhelm Scheele was the first person to isolate chlorine gas and study it. Therefore, he is credited with discovering chlorine in 1774. He did not realize that the gas was an element.
What are the characteristics of chlorine?
Chlorine is a toxic gas that irritates the skin, the eyes and the respiratory system. Characteristics: Chlorine is a greenish-yellow, diatomic, dense gas with a sharp smell (the smell of bleach). It is not found free in nature as it combines readily with nearly all other elements.
