  2. Rutherfordium - Wikipedia

    en.wikipedia.org/wiki/Rutherfordium

    Rutherfordium is expected to have the electron configuration [Rn]5f 14 6d 2 7s 2 and therefore behave as the heavier homologue of hafnium in group 4 of the periodic table. It should therefore readily form a hydrated Rf 4+ ion in strong acid solution and should readily form complexes in hydrochloric acid, hydrobromic or hydrofluoric acid ...

  3. Electron configurations of the elements (data page) - Wikipedia

    en.wikipedia.org/wiki/Electron_configurations_of...

    The Chemistry of the Actinide and Transactinide Elements (3rd ed.). Dordrecht, The Netherlands: Springer Science+Business Media. p. 1722. ISBN 1-4020-3555-1. This book contains predicted electron configurations for the elements up to 172, as well as 184, based on relativistic Dirac–Fock calculations by B. Fricke in Fricke, B. (1975). Dunitz ...

  4. Periodic table (electron configurations) - Wikipedia

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

    Note that these electron configurations are given for neutral atoms in the gas phase, which are not the same as the electron configurations for the same atoms in chemical environments. In many cases, multiple configurations are within a small range of energies and the small irregularities that arise in the d- and f-blocks are quite irrelevant ...

  5. Electron configuration - Wikipedia

    en.wikipedia.org/wiki/Electron_configuration

    In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. [1] For example, the electron configuration of the neon atom is 1s 2 2s 2 2p 6 , meaning that the 1s, 2s, and 2p subshells are occupied by two, two, and six ...

  6. Group 4 element - Wikipedia

    en.wikipedia.org/wiki/Group_4_element

    Like other groups, the members of this family show patterns in their electron configurations, especially the outermost shells, resulting in trends in chemical behavior. Most of the chemistry has been observed only for the first three members of the group; chemical properties of rutherfordium are not well-characterized, but what is known and ...

  7. Term symbol - Wikipedia

    en.wikipedia.org/wiki/Term_symbol

    n′ℓ is an attempt to describe electronic configuration of the excited electron in a way of describing electronic configuration of hydrogen atom. # is an additional number denoted to each energy level of given n′ℓ (there can be multiple energy levels of given electronic configuration, denoted by the term symbol).

  8. Group 9 element - Wikipedia

    en.wikipedia.org/wiki/Group_9_element

    Group 9, by modern IUPAC numbering, [1] is a group (column) of chemical elements in the d-block of the periodic table.Members of Group 9 include cobalt (Co), rhodium (Rh), iridium (Ir) and meitnerium (Mt). [2]

  9. Extended periodic table - Wikipedia

    en.wikipedia.org/wiki/Extended_periodic_table

    The collapse of the 5g orbital itself is delayed until around element 125 (unbipentium or eka-neptunium); the electron configurations of the 119-electron isoelectronic series are expected to be [Og]8s 1 for elements 119 through 122, [Og]6f 1 for elements 123 and 124, and [Og]5g 1 for element 125 onwards.
