List of chemical elements

118 <a href="/facts/Chemical_element/0jducgWD">chemical elements</a> have been <a href="/facts/Timeline_of_chemical_element_discoveries/QY4X2RP3">identified</a> and named officially by <a href="/facts/International_Union_of_Pure_and_Applied_Chemistry/2AV6myCK">IUPAC</a>. A chemical element, often simply called an element, is a type of <a href="/facts/Atom/FoQ4kGN5">atom</a> which has a specific number of <a href="/facts/Proton/clCjepXP">protons</a> in its <a href="/facts/Atomic_nucleus/orpIm5Xl">atomic nucleus</a> (i.e., a specific <a href="/facts/Atomic_number/bgAr581S">atomic number</a>, or Z).
The definitive visualisation of all 118 elements is the <a href="/facts/Periodic_table/umdGIfUb">periodic table of the elements</a>, whose <a href="/facts/History_of_the_periodic_table/54vj6AVe">history</a> along the principles of the <a href="/facts/Periodic_law/dI0mkSju">periodic law</a> was one of the founding developments of modern <a href="/facts/Chemistry/SrNqkGVm">chemistry</a>. It is a tabular arrangement of the elements by their chemical properties that usually uses abbreviated <a href="/facts/Chemical_symbol/2Fe1VAL0">chemical symbols</a> in place of full element names, but the linear list format presented here is also useful. Like the periodic table, the list below organizes the elements by the number of protons in their atoms; it can also be organized by other properties, such as <a href="/facts/Atomic_weight/A3vbuz2n">atomic weight</a>, <a href="/facts/Density/92p6hh9I">density</a>, and <a href="/facts/Electronegativity/H7Vq7Uah">electronegativity</a>.
