§ s w. s m Part 6 - Personal Periodic Table On your personal The periodic table is one of the cornerstones of chemistry because it organizes all the known elements on the basis of their chemical properties. A modern version is shown in Figure \(\PageIndex{1}\). Most periodic tables provide additional data (such as atomic mass) in a box that contains each element’s symbol.
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 48 Ca and 249 Bk fusion reaction at the gas-filled recoil separator TASCA at GSI Darmstadt, Germany.
PubChem is working with IUPAC to help make information about the elements and the periodic table machine-readable. The modern periodic table is sometimes expanded into its long or 32-column form by reinstating the footnoted f-block elements into their natural position between the s- and d-blocks, as proposed by Alfred Werner in 1905. Unlike the 18-column form, this arrangement results in "no interruptions in the sequence of increasing atomic numbers". 11 Na Sodium 22.990; 12 Mg Magnesium 24.305; 13 Al Aluminium 26.982; 14 Si Silicon 28.085; 15 P Phosphorus 30.974; 16 S Sulfur 32.06; 17 Cl Chlorine 35.45; 18 Ar Argon 39.948 The first 10 elements are as follows- Hydrogen (H), Helium (He), Lithium (Li), Beryllium (Be), Boron (B), Carbon (C), Nitrogen (N), Oxygen (O), Fluorine (F), Neon (Ne).

The periodic table (also known as the periodic table of elements) is organized so scientists can quickly discern the properties of individual elements such as their mass, electron number, electron configuration and their unique chemical properties. Metals reside on the left side of the table, while non-metals reside on the right. Finally, IUPAC assigns collective names (lanthanoids and actinoids) and group numbering (1 to 18) and has investigated the membership of the group 3 elements. PubChem is working with IUPAC to help make information about the elements and the periodic table machine-readable.
