As part Interactive periodic table with up-to-date element property data collected from authoritative sources. Look up chemical element names, symbols, atomic masses and other properties, visualize trends, or even test your elements knowledge by playing a periodic table game! The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties.

Learn who made the periodic table, why he arranged the elements this way and about the important groups you need to know.

Name chemical element: Symbol: Atomic number - Name alphabetically: 1.0079: Hydrogen: H: 1 - Atomic number: 4.0026: Helium: He: 2 - Symbol: 6.941: Lithium: Li: 3 - Atomic Mass: 9.0122: Beryllium: Be: 4 - Electronegativity: 10.811: Boron: B: 5 - Density: 12.0107: Carbon: C: 6 - Melting point: 14.0067: Nitrogen: N: 7 - Boiling point: 15.9994: Oxygen: O: 8 - Vanderwaals radius: 18.9984 Please note that the elements do not show their natural relation towards each other as in the Periodic system. There you can find the metals, semi-conductor(s), non-metal(s), inert noble gas(ses), Halogens, Lanthanoides, Actinoids (rare earth elements) and transition metals. Calcium: Ca: 20: Californium: Cf: 98: Carbon: C: 6: Cerium: Ce: 58: Cesium: Cs: 55: Chlorine: Cl: 17: Chromium: Cr Charles Janet 's left-step periodic table is the most widely used alternative to the traditional depiction of the periodic system.

The table lists only the first IE in eV units. To convert to kJ/mol multiply by 96.4869. Reference: NIST Reference Table on Ground states and ionization energies for the neutral atoms. IE decreases going down a column of the periodic table, and increases from left to right in a row.

A period in the periodic table is a row of chemical elements.All elements in a row have the same number of electron shells.Each next element in a period has one more proton and is less metallic than its predecessor. Arranged this way, groups of elements in the same column have similar chemical and physical properties, reflecting the periodic law. The periodic table is an arrangement of the chemical elements, structured by their atomic number, electron configuration and recurring chemical properties.In the basic form, elements are presented in order of increasing atomic number, in the reading sequence. Then, rows and columns are created by starting new rows and inderting blank cells, so that rows and columns show elements with recurring Are you struggling with organic chemistry?

An enormous number of words are possible, so if you have an addition to make to the list, feel free to post a reply. The Periodic Table of DevOps Tools is the industry's go-to resource for identifying best-of-breed tools across the software delivery lifecycle. Created by DevOps practitioners for DevOps practitioners, over 18,000 votes were cast across more than 400 products in 17 categories to produce the 2020 Periodic Table of DevOps Tools. This color periodic table shows the relative sizes of each atom. The diameter of each atom is scaled relative to the largest element atom: cesium.
