This is a list of the 118 chemical elements which have been identified as of 2021. A chemical element, often simply called an element, is a species of atoms which all have the same number of protons in their atomic nuclei. A popular visualization of all 118 elements is the periodic table of the elements, a convenient tabular arrangement of the elements by their chemical properties that uses abbreviated chemical symbols in place of full element names, but the simpler list format

Nonetheless, this transformation has not found frequent An isotope is a variant of an element in which it has an equal number or protons but a varied number of neutrons. The notation of an isotope occurs by adding a subscipt and superscript to the left side of an element such as 238 92U (uranium isotope) UNE stands for Unnilennium (chemistry; synthetic element of periodic table) Suggest new definition This definition appears frequently and is found in the following Acronym Finder categories: 2021-04-23 · An exact search will retrieve substances containing only the elements drawn. For the search to work, it needs to contain some less common elements: if you just search for C, H, O, N, S, for example, it will obviously retrieve many millions of substances and fail. Reaxys has a formula builder that allows element selection.
