List of chemical elements - wikipedia List of chemical elements The 118 identified chemical elements This article 's lead section does not adequately summarize key points of its contents . Please consider expanding the lead to provide an accessible overview of all important aspects of the article . Please discuss this issue on the article 's talk page . ( October 2016 ) As of September 2018 , 118 chemical elements are identified . A chemical element or element is a species of atoms having the same number of protons in their atomic nuclei ( i.e. the same atomic number , or Z ) . Therefore , the elements can be listed by the number of protons in the atom of each element as listed below .

Jump up ^ Unless otherwise indicated , elements are primordial -- they occur naturally , and not through decay . ^ Jump up to : The isotopic composition of this element varies in some geological specimens , and the variation may exceed the uncertainty stated in the table . ^ Jump up to : The isotopic composition of the element can vary in commercial materials , which can cause the atomic weight to deviate significantly from the given value . ^ Jump up to : The isotopic composition varies in terrestrial material such that a more precise atomic weight can not be given . ^ Jump up to : The value listed is the conventional atomic - weight value suitable for trade and commerce . The actual value may differ depending on the isotopic composition of the sample . Since 2009 , IUPAC provides the standard atomic - weight values for these elements using the interval notation . The corresponding standard atomic weights are : Hydrogen : ( 1.00784 , 1.00811 ) Lithium : ( 6.938 , 6.997 ) Boron : ( 10.806 , 10.821 ) Carbon : ( 12.0096 , 12.0116 ) Nitrogen : ( 14.00643 , 14.00728 ) Oxygen : ( 15.99903 , 15.99977 ) Magnesium : ( 24.304 , 24.307 ) Silicon : ( 28.084 , 28.086 ) Sulfur : ( 32.059 , 32.076 ) Chlorine : ( 35.446 , 35.457 ) Bromine : ( 79.901 , 79.907 ) Thallium : ( 204.382 , 204.385 ) Jump up ^ Helium does not solidify at a pressure of one atmosphere . Helium can only solidify at pressures above 25 atmospheres , which corresponds to a melting point of absolute zero . Jump up ^ The atomic weight of commercial lithium can vary between 6.939 and 6.996 -- analysis of the specific material is necessary to find a more accurate value . Jump up ^ This element sublimes at one atmosphere of pressure . ^ Jump up to : The element does not have any stable nuclides , and a value in brackets , e.g. ( 209 ) , indicates the mass number of the longest - lived isotope of the element . However , four such elements , bismuth , thorium , protactinium , and uranium , have characteristic terrestrial isotopic compositions , and thus their standard atomic weights are given . ^ Jump up to : This element is transient -- it occurs only through decay . ^ Jump up to : This element is synthetic -- the transuranic elements 95 and above do not occur naturally , but they can all be produced artificially . ^ Jump up to : The value has not been precisely measured , usually because of the element 's short half - life ; the value given in parentheses is a prediction . Jump up ^ With error bars : 357 K . Jump up ^ This predicted value is for liquid oganesson , not gaseous oganesson .
