Davy is best known for his research in the field of electrochemistry and his discovery and isolation of the alkali metals potassium and sodium in 1807. Alkali metals are noted for how vigorously they react with water. The metal is recovered when ammonia is evaporated from metal solutions. Alkali metals are in group IA on the far left side of the periodic table. Potassium was discovered in 1807 by Sir Humphry Bartholomew Davy. Although often listed in Group 1 due to its electronic configuration, hydrogen is not technically an alkali metal since it rarely exhibits similar behavior. Qualitative analysis of alkali metals is possible by means of flame reactions using characteristic luminescence lines. He was originally apprenticed as a surgeon, but instead took up chemistry in the pharmacy. The liquid ammonia solution of an alkali metal is conductive and paramagnetic. The nonmetal element group is a subset of these elements. Perhaps the most common use, to many people, is in NaCl, or table salt. The gaseous state of the 1 mole metal. a Group 1 is composed of hydrogen (H) and the alkali metals. It is the most common element in the universe. Potassium. Here is the full list of metals in group one (+1 charge): Lithium (Li). Potassium (1807) and subsequently sodium were isolated by the electrolysis of molten salt of KOH or NaOH by H. Davy in the 19th century. Alkali metals are highly reactive at standard temperature and pressure and readily lose their outermost electron to form cations with charge +1. At a young age he attended the University of Uppsala and earned degrees in law and mineralogy. Alkali metals have one valence electron. The elements in group 13 and group 15 form a cation with a -3 charge each. Although often listed in Group 1 due to its electronic configuration, hydrogen is not technically an alkali metal since it rarely exhibits similar behavior. Sodium is also used in the paper, textile, and petroleum industries. As shown in Table \(\PageIndex{1}\), melting-points, boiling points, and densities of alkali metals are low, and they are soft metals. During his life, Kirchoff laid out many laws relating to physics. Arfwedson was born in 1792 to a wealthy family in Sweden. Francium was discovered in 1939 by Marguerite Perey. The alkali metals make up Group 1 of the periodic table. Hydrogen is usually placed at the top of the Group but is not a Group 1 metal. Sodium (Na). The Group 1 elements in the periodic table are known as the alkali metals. With this degree, she joined the Radium Institute where she served as a personal assistant to Marie Curie.
