2019-12-05 · A chemical element is a substance consisting of only one type of atom. In other words, all atoms in an element contain the same number of protons. The identity of a chemical element cannot be changed by any chemical reaction. However, a nuclear reaction can transmute one element into another one. 2020-10-22 · Of the known elements, 11 (hydrogen, nitrogen, oxygen, fluorine, chlorine, and the six noble gases) are gases under ordinary conditions, two (bromine and mercury) are liquids (two more, cesium and gallium, melt at about or just above room temperature), and the rest are solids. The chemistry tutorial video explains chemical elements as it shows how the entire Universe is built from just 92 different kinds of atoms, but that these at there are many meanings of k in chemistry. 1.k is the chemical symbol of element potassium.

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.
