SymbolNameOrigin of SymbolAtomic NumberAtomic MassGroupPeriodAcActiniumGreek aktinos89[227]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, three elements, Thorium, Protactinium, and Uranium, have a characteristic terrestrial isotopic composition, and thus their atomic mass given. 7AgSilverLatin argentum47107.8682(2)The isotopic composition of this element varies in some geological specimens, and the variation may exceed the uncertainty stated in the table.115AlAluminium (Aluminum)Latin alumen1326.9815386(8)133AmAmericiumthe Americas95[243] 7ArArgonGreek argon1839.948(1)The isotopic composition varies in terrestrial material such that a more precise atomic weight can not be given.183|}AsArsenicGreek arsenikos3374.92160(2)154AtAstatineGreek astatos85[210]176AuGoldLatin aurum79196.966569(4)116BBoronborax and carbon510.811(7)The isotopic composition of the element can vary in commercial materials, which can cause the atomic weight to deviate significantly from the given value.132BaBariumGreek barys56137.327(7)26BeBerylliumberyl49.012182(3)22BhBohriumNiels Bohr107[264]77BiBismuthcorruption of the German wissmuth83208.98040(1)156BkBerkeliumBerkeley, California97[247] 7BrBromineGreek bromos3579.904(1)174CCarbonLatin carbo612.0107(8)142CaCalciumLatin calx2040.078(4)24CdCadmiumGreek kadmia48112.411(8)125CeCeriumCeres58140.116(1) 6CfCaliforniumState and University of California98[251] 7ClChlorineGreek chloros1735.453(2)173CmCuriumPierre and মারি ক্যুরি96[247] 7CoCobaltGerman kobold2758.933195(5)94CrChromiumGreek chroma2451.9961(6)64CsCaesium (Cesium)Latin caesius55132.9054519(2)16CuCopperLatin Cuprum2963.546(3)114DbDubniumDubna, Russia105[262]57DsDarmstadtiumDarmstadt, Germany110[271]107DyDysprosiumGreek dysprositos66162.500(1) 6ErErbiumYtterby, Sweden68167.259(3) 6EsEinsteiniumAlbert Einstein99[252] 7EuEuropiumEurope63151.964(1) 6FFluorineLatin fluo918.9984032(5)172FeIronLatin ferrum2655.845(2)84FmFermiumEnrico Fermi100[257] 7FrFranciumFrance87[223]17GaGalliumLatin Gallia3169.723(1)134GdGadoliniumgadolinite64157.25(3) 6GeGermaniumGermany3272.64(1)144HHydrogenGreek hydror and gen11.00794(7)11HeHeliumGreek helios24.002602(2)181HfHafniumLatin Hafnia72178.49(2)46HgMercuryLatin hydrargyrum80200.59(2)126HoHolmiumLatin Holmia67164.930 32(2) 6HsHassiumHesse, Germany108[277]87IIodineGreek ioeides53126.904 47(3)175InIndiumindigo blue49114.818(3)135IrIridiumGreek iris77192.217(3)96KPotassium (Kalium)Latin kalium1939.0983(1)14KrKryptonGreek kryptos3683.798(2)184LaLanthanumGreek lanthanien57138.90547(7) 6LiLithiumGreek lithos36.941(2)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.12LrLawrenciumErnest O.
