  • Lanthanides are also known as "rare earth elements", a deprecated term. Regarding group membership of these elements, see here.
  • Alkali metals, alkaline earth metals, transition metals, actinides, lanthanides, and poor metals are all collectively known as "metals".
  • Halogens and noble gases are also non-metals.
  • State at standard temperature and pressure (0 °C and 1 atm): Gases Liquids Solid
  • Natural occurrence: Undiscovered
    Synthetic
    From decay Primordial

Step-By-Step Procedure

  • The standard table (same as above) provides the basics.
  • A vertical table scrolls down for narrow pages.
  • The big table provides the basics and full element names.
  • The huge table provides the above and atomic masses.
  • The Electronegativity table provides electronegativities.
  • This table sets inline the f-block of lanthanides and actinides.
  • Electron configurations
  • Metals and non-metals
  • The blocks are shaded instead of series.
  • The valences are shaded instead of series.

Step-By-Step Procedure

The layout of the periodic table demonstrates recurring ("periodic") chemical properties. Elements are listed in order of increasing atomic number (i.e. the number of protons in the atomic nucleus). Rows are arranged so that elements with similar properties fall into the same vertical columns ("groups"). According to quantum mechanical theories of electron configuration within atoms, each horizontal row ("period") in the table corresponded to the filling of a quantum shell of electrons. There are progressively longer periods further down the table, grouping the elements into s-, p-, d- and f-blocks to reflect their electron configuration. In printed tables, each element is usually listed with its element symbol and atomic number; many versions of the table also list the element's atomic mass and other information, such as its abbreviated electron configuration, electronegativity and most common valence numbers.
