What are the variable valencies of copper?
Copper is one of the transition elements and thus exhibits variable oxidation states. It has two valencies: +1 and +2 and the corresponding atoms are termed as Cuperous (+1 valency) and Cupric (+2 valency). These are also denoted as Cu(I) and Cu(II).
Why is copper so important?
Copper is an essential trace mineral necessary for survival. It is found in all body tissues and plays a role in making red blood cells and maintaining nerve cells and the immune system. It also helps the body form collagen and absorb iron, and plays a role in energy production.
Who invented copper?

Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
