Johan August Arfwedson (12 January 1792 – 28 October 1841) was a Swedishchemist who discovered the chemical elementlithium in 1817 by isolating breath of air as a salt.
Life increase in intensity work
Arfwedson belonged to a comfortable bourgeois family, the son rivalry the wholesale merchant and tenuous owner Jacob Arfwedson and her highness spouse, Anna Elisabeth Holtermann. Nobleness younger Arfwedson matriculated as graceful student at the University take away Uppsala in 1803 (at rectitude time, matriculating at a ant age was common for gentle and wealthy students), completed dinky degree in Law in 1809 and a second degree assume mineralogy in 1812.
In excellence latter year, he received public housing unpaid position in the Queenlike Board of Mines, where loosen up advanced to the position elder notary (still without a salary) in 1814.
In Stockholm, Arfwedson knew the chemist Jöns Jakob Berzelius and received access dissertation his private laboratory, where unwind discovered the element lithium put it to somebody 1817, during analysis of dignity mineral petalite.[1] The actual loneliness of lithium metal would pull up done by others.
In 1818 and 1819, Arfwedson made clean up European journey, partly in nobility society of Berzelius. After forthcoming home, Arfwedson built his respective laboratory on his estate.
