  2. File:The Periodic Table of the Elements in Pictures.pdf

    en.wikipedia.org/wiki/File:The_Periodic_Table_of...

    The Periodic Table of the Elements in Pictures.pdf. English: This pictorial periodic table is colorful, boring, and packed with information. In addition to the element's name, symbol, and atomic number, each element box has a drawing of one of the element's main human uses or natural occurrences. The table is color-coded to show the chemical ...

  3. Periodic table - Wikipedia

    en.wikipedia.org/wiki/Periodic_table

    The periodic table is a graphic description of the periodic law, which states that the properties and atomic structures of the chemical elements are a periodic function of their atomic number. Elements are placed in the periodic table according to their electron configurations , [41] the periodic recurrences of which explain the trends in ...

  4. Block (periodic table) - Wikipedia

    en.wikipedia.org/wiki/Block_(periodic_table)

    e. A block of the periodic table is a set of elements unified by the atomic orbitals their valence electrons or vacancies lie in. [1] The term seems to have been first used by Charles Janet. [2] Each block is named after its characteristic orbital: s-block, p-block, d-block, f-block and g-block . The block names (s, p, d, and f) are derived ...

  5. List of data references for chemical elements - Wikipedia

    en.wikipedia.org/wiki/List_of_data_references...

    List of chemical elements — with basic properties like standard atomic weight, m.p., b.p., abundance. Abundance of the chemical elements. Abundances of the elements (data page) — Earth's crust, sea water, Sun and Solar System. Abundance of elements in Earth's crust. Atomic radii of the elements (data page) — atomic radius (empirical ...

  6. Periodic table (electron configurations) - Wikipedia

    en.wikipedia.org/wiki/Periodic_table_(electron...

    The construction of the periodic table ignores these irregularities and is based on ideal electron configurations. Note the non-linear shell ordering, which comes about due to the different energies of smaller and larger shells. References. See list of sources at Electron configurations of the elements (data page)

  7. List of chemical elements - Wikipedia

    en.wikipedia.org/wiki/List_of_chemical_elements

    List of chemical elements. 118 chemical elements have been identified and named officially by IUPAC. A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z ). [1]

  8. Atomic radii of the elements (data page) - Wikipedia

    en.wikipedia.org/wiki/Atomic_radii_of_the...

    Atomic radii vary in a predictable and explicable manner across the periodic table. For instance, the radii generally decrease rightward along each period (row) of the table, from the alkali metals to the noble gases; and increase down each group (column). The radius increases sharply between the noble gas at the end of each period and the ...
