K chemistry element

Krypton was one of three noble gases discovered in 1898 by Scottish chemist and physicist Sir William Ramsay (1852-1916) and English chemist Morris William Travers (1872-1961). Ramsay and Travers discovered the gases by allowing liquid air to evaporate. This chapter discusses the discovery, isolation, abundance, and distribution of the alkali metals—lithium, sodium, potassium, rubidium, cesium, and francium. The group 1 elements are soft, low-melting metals that crystallize with bcc lattices.

How to calculate K, and how to use K to determine if a reaction strongly favors products or reactants at equilibrium. In addition, any new element must be assigned a temporary name and symbol, and if validated, given an official name. Such was the case when IUPAC recently reviewed elements 113, 115, 117 and 118, and decided to give them official names and symbols (goodbye, ununseptium and hello, tennessine!).

Put your understanding of this concept to test by answering a few MCQs. Potassium gets its name from the salt potash from which potassium was first isolated. The K symbol for the element comes from the Latin word "kalium", which means potash. Isotopes There are three isotopes of potassium that occur naturally: K-39, 40, and 41.
