  2. Transition metal - Wikipedia

    en.wikipedia.org/wiki/Transition_metal

    As implied by the name, all transition metals are metals and thus conductors of electricity. In general, transition metals possess a high density and high melting points and boiling points. These properties are due to metallic bonding by delocalized d electrons, leading to cohesion which increases with the number of shared electrons. However ...

  4. Charge-transfer band - Wikipedia

    en.wikipedia.org/wiki/Charge-transfer_band

    Charge-transfer bands of transition metal complexes result from shift of charge density between molecular orbitals (MO) that are predominantly metal in character and those that are predominantly ligand in character. If the transfer occurs from the MO with ligand-like character to the metal-like one, the transition is called a ligand-to-metal ...

  5. Platinum group - Wikipedia

    en.wikipedia.org/wiki/Platinum_group

    The platinum-group metals (PGMs), also known as the platinoids, platinides, platidises, platinum group, platinum metals, platinum family or platinum-group elements (PGEs), are six noble, precious metallic elements clustered together in the periodic table. These elements are all transition metals in the d-block (groups 8, 9, and 10, periods 5 ...

  6. Group 5 element - Wikipedia

    en.wikipedia.org/wiki/Group_5_element

    This group is sometimes called the vanadium group or vanadium family after its lightest member; however, the group itself has not acquired a trivial name because it belongs to the broader grouping of the transition metals. As is typical for early transition metals, niobium and tantalum have only the group oxidation state of +5 as a major one ...

  7. List of elements by atomic properties - Wikipedia

    en.wikipedia.org/wiki/List_of_elements_by_atomic...

    This is a list of chemical elements and their atomic properties, ordered by atomic number (Z).. Since valence electrons are not clearly defined for the d-block and f-block elements, there not being a clear point at which further ionisation becomes unprofitable, a purely formal definition as number of electrons in the outermost shell has been used.

  8. Oxidation state - Wikipedia

    en.wikipedia.org/wiki/Oxidation_state

    The oxidation state in compound naming for transition metals and lanthanides and actinides is placed either as a right superscript to the element symbol in a chemical formula, such as Fe III or in parentheses after the name of the element in chemical names, such as iron(III). For example, Fe 2 (SO 4)

  9. Group 3 element - Wikipedia

    en.wikipedia.org/wiki/Group_3_element

    Group 3 is the first group of transition metals in the periodic table.This group is closely related to the rare-earth elements.It contains the four elements scandium (Sc), yttrium (Y), lutetium (Lu), and lawrencium (Lr).
