  2. Periodic table - Wikipedia

    en.wikipedia.org/wiki/Periodic_table

    The periodic table, also known as the periodic table of the elements, is an ordered arrangement of the chemical elements into rows (" periods ") and columns (" groups "). It is an icon of chemistry and is widely used in physics and other sciences. It is a depiction of the periodic law, which states that when the elements are arranged in order ...

  3. List of chemical elements - Wikipedia

    en.wikipedia.org/wiki/List_of_chemical_elements

    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 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...

    He used the table to predict the properties of then unknown elements. While his hit rate was less than 50% it was his successes that propelled the widespread acceptance of the idea of a periodic table of the chemical elements. [8] The eight-column style remains popular to this day, most notably in Russia, Mendeleev's country of birth.

  5. Group (periodic table) - Wikipedia

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

    Group (periodic table) In the periodic table of the elements, each column is a group. In chemistry, a group (also known as a family) [ 1 ] is a column of elements in the periodic table of the chemical elements. There are 18 numbered groups in the periodic table; the 14 f-block columns, between groups 2 and 3, are not numbered.

  6. Extended periodic table - Wikipedia

    en.wikipedia.org/wiki/Extended_periodic_table

    e. An extended periodic table theorizes about chemical elements beyond those currently known and proven. The element with the highest atomic number known is oganesson (Z = 118), which completes the seventh period (row) in the periodic table. All elements in the eighth period and beyond thus remain purely hypothetical.

Seaborg —after whom the element seaborgium is named—standing in front of a periodic table, May 19, 1950 Part of a series on the Periodic table Periodic table forms 18-column 32-column Alternative and extended ...

  8. Period (periodic table) - Wikipedia

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

    In the periodic table of the elements, each numbered row is a period. A period on 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, elements in the same group (column ...

  9. Group 8 element - Wikipedia

    en.wikipedia.org/wiki/Group_8_element

    primordial element. synthetic element. Group 8 is a group (column) of chemical elements in the periodic table. It consists of iron (Fe), ruthenium (Ru), osmium (Os) and hassium (Hs). [1] ". Group 8" is the modern standard designation for this group, adopted by the IUPAC in 1990. [1] It should not be confused with "group VIIIA" in the CAS system ...
