WebElements Elements Compounds Shop Printable periodic table The periodic table of the elementsThe periodic table is an arrangment of the chemical elements ordered by atomic number so that periodic properties of the elements (chemical periodicity) are made clear.Explore the chemical elements through this periodic table Group 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 Period1 1 H 1.008 Hydrogen 2 He 4.0026 Helium 2 3 Li 6.94 Lithium 4 Be 9.0122 Beryllium 5 B 10.81 Boron 6 C 12.011 Carbon 7 N 14.007 Nitrogen 8 O 15.999 Oxygen 9 F 18.998 Fluorine 10 Ne 20.180 Neon 3 11 Na 22.990 Sodium 12 Mg 24.305 Magnesium 13 Al 26.982 Aluminium 14 Si 28.085 Silicon 15 P 30.974 Phosphorus 16 S 32.06 Sulfur 17 Cl 35.45 Chlorine 18 Ar 39.948 Argon 4 19 K 39.098 Potassium 20 Ca 40.078 Calcium 21 Sc 44.956 Scandium 22 Ti 47.867 Titanium 23 V 50.942 Vanadium 24 Cr 51.996 Chromium 25 Mn 54.938 Manganese 26 Fe 55.845 Iron 27 Co 58.933 Cobalt 28 Ni 58.693 Nickel 29 Cu 63.546 Copper 30 Zn 65.38 Zinc 31 Ga 69.723 Gallium 32 Ge 72.630 Germanium 33 As 74.922 Arsenic 34 Se 78.971 Selenium 35 Br 79.904 Bromine 36 Kr 83.798 Krypton 5 37 Rb 85.468 Rubidium 38 Sr 87.62 Strontium 39 Y 88.906 Yttrium 40 Zr 91.224 Zirconium 41 Nb 92.906 Niobium 42 Mo 95.95 Molybdenum 43 Tc ☢ 96.906 Technetium 44 Ru 101.07 Ruthenium 45 Rh 102.91 Rhodium 46 Pd 106.42 Palladium 47 Ag 107.87 Silver 48 Cd 112.41 Cadmium 49 In 114.82 Indium 50 Sn 118.71 Tin 51 Sb 121.76 Antimony 52 Te 127.60 Tellurium 53 I 126.90 Iodine 54 Xe 131.29 Xenon 6 55 Cs 132.91 Caesium 56 Ba 137.33 Barium * 71 Lu 174.97 Lutetium 72 Hf 178.49 Hafnium 73 Ta 180.95 Tantalum 74 W 183.84 Tungsten 75 Re 186.21 Rhenium 76 Os 190.23 Osmium 77 Ir 192.22 Iridium 78 Pt 195.08 Platinum 79 Au 196.97 Gold 80 Hg 200.59 Mercury 81 Tl 204.38 Thallium 82 Pb 207.2 Lead 83 Bi 208.98 Bismuth 84 Po ☢ 208.98 Polonium 85 At ☢ 209.99 Astatine 86 Rn ☢ 222.02 Radon 7 87 Fr ☢ 223.02 Francium 88 Ra ☢ 226.03 Radium ** 103 Lr ☢ 262.11 Lawrencium 104 Rf ☢ 267.12 Rutherfordium 105 Db ☢ 270.13 Dubnium 106 Sg ☢ 269.13 Seaborgium 107 Bh ☢ 270.13 Bohrium 108 Hs ☢ 269.13 Hassium 109 Mt ☢ 278.16 Meitnerium 110 Ds ☢ 281.17 Darmstadtium 111 Rg ☢ 281.17 Roentgenium 112 Cn ☢ 285.18 Copernicium 113 Nh ☢ 286.18 Nihonium 114 Fl ☢ 289.19 Flerovium 115 Mc ☢ 289.20 Moscovium 116 Lv ☢ 293.20 Livermorium 117 Ts ☢ 293.21 Tennessine 118 Og ☢ 294.21 Oganesson *Lanthanoids * 57 La 138.91 Lanthanum 58 Ce 140.12 Cerium 59 Pr 140.91 Praseodymium 60 Nd 144.24 Neodymium 61 Pm ☢ 144.91 Promethium 62 Sm 150.36 Samarium 63 Eu 151.96 Europium 64 Gd 157.25 Gadolinium 65 Tb 158.93 Terbium 66 Dy 162.50 Dysprosium 67 Ho 164.93 Holmium 68 Er 167.26 Erbium 69 Tm 168.93 Thulium 70 Yb 173.05 Ytterbium **Actinoids ** 89 Ac ☢ 227.03 Actinium 90 Th ☢ 232.04 Thorium 91 Pa ☢ 231.04 Protactinium 92 U ☢ 238.03 Uranium 93 Np ☢ 237.05 Neptunium 94 Pu ☢ 244.06 Plutonium 95 Am ☢ 243.06 Americium 96 Cm ☢ 247.07 Curium 97 Bk ☢ 247.07 Berkelium 98 Cf ☢ 251.08 Californium 99 Es ☢ 252.08 Einsteinium 100 Fm ☢ 257.10 Fermium 101 Md ☢ 258.10 Mendelevium 102 No ☢ 259.10 Nobelium The standard form of the periodic table shown here includes periods (shown horizontally) and groups (shown vertically). The properties of elements in groups are similar in some respects to each other. There is no one single or best structure for the periodic table but by whatever consensus there is, the form used here is very useful and the most common. The periodic table is a masterpiece of organised chemical information and the evolution of chemistry's periodic table into the current form is an astonishing achievement. The International Union of Pure and Applied Chemistry (IUPAC) confirmed the names of elements 113, 115, 117, and 118 as: Nihonium (symbol Nh), for element 113 Moscovium (symbol Mc), for element 115 Tennessine (symbol Ts), for element 117 Oganesson (symbol Og), for element 118 This followed a 5-month period of public review after which the names earlier proposed by the discoverers were approved by IUPAC. You can buy this periodic table poster and more at the WebElements periodic table shop. On 1 May 2014 a paper published in Phys. Rev. Lett by J. Khuyagbaatar and others states the superheavy element with atomic number Z = 117 (ununseptium) was produced as an evaporation residue in the 48Ca and 249Bk fusion reaction at the gas-filled recoil separator TASCA at GSI Darmstadt, Germany. The radioactive decay of evaporation residues and their -decay products was studied using a detection setup that allows measurement of decays of single atomic nuclei with very short half-lives. Two decay chains comprising seven -decays and a spontaneous fission each were identified and assigned to the isotope 294Uus (element 117) and its decay products.
