The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties.The structure of the table shows periodic trends.The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right.

Potassium is a chemical element with the symbol K (from Neo-Latin kalium) and atomic number 19. Potassium is a silvery-white metal that is soft enough to be cut with a knife with little force. [5] Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure.

K chemistry element

Potassium is essential to several aspects of plant, animal, and human life and is Latin name for an element is used as the basis for its symbol, for instance K represents potassium (kalium in Latin). Three subatomic particles compose elements: protons, neutrons, and electrons. Protons, which have an electrical charge of +1, and neutrons, which have a neutral charge, make up the nucleus of an element. This video explains the Elements and Compounds.

Gallium, Chemical Element . In the late 1860s Russian chemist Dmitri Mendeleev (1834-1907) made one of the greatest discoveries in modern chemistry: the periodic law. The periodic law describes how chemical elements are related to each other. Germanium, Chemical Element . Germanium is a metalloid. Vitamin K, any of several fat-soluble naphthoquinone compounds. Vitamin K (from the Danish word koagulation) is required for the synthesis of several blood clotting factors, including prothrombin and factors VII, IX, and X. A form of vitamin K known as phylloquinone (vitamin K1) is synthesized by PubChem is the world's largest collection of freely accessible chemical information.

Efforts to synthesise new elements are continuing. With such a large number of elements it is very difficult to study individually the chemistry of all these elements and their innumerable compounds individually. 12 Aug 2020 Potassium is the first element of the fourth period. Know the Uses of Potassium, Chemical Properties of Potassium, Atomic Mass, Melting Point, The chemical element potassium is classed as an alkali metal . It was discovered in 1806 by Sir Humphry Davy.
