{{Main|List of chemical elements}}
The following sortable table shows the 118 known elements.
* '''Atomic number''', '''Element''', and '''Symbol''' all serve independently as unique identifiers.
* '''Element''' names are those accepted by [[IUPAC]]. <!-- ; provisional names for recently produced elements not yet formally named are in parentheses. -->
* '''Block''' indicates the periodic table [[Block (periodic table)|block]] for each element: red = s-block, yellow = p-block, blue = d-block, green = f-block.
* '''Group''' and '''period''' refer to an element's position in the periodic table. Group numbers here show the currently accepted numbering; for older numberings, see [[Group (periodic table)]].
