  2. Mercury (element) - Wikipedia

    en.wikipedia.org/wiki/Mercury_(element)

    Mercury has been replaced with safer compounds in most, if not all, of these applications. It was allegedly used by allied spies to sabotage Luftwaffe planes: a mercury paste was applied to bare aluminium, causing the metal to rapidly corrode; this would cause structural failures. [123] Mercury was once used as a gun barrel bore cleaner. [124 ...

    However, mercury can easily be reduced to the +1 oxidation state; usually, as in the ion Hg 2+ 2, two mercury(I) ions come together to form a metal-metal bond and a diamagnetic species. [24] Cadmium can also form species such as [Cd 2 Cl 6] 4− in which the metal's oxidation state is +1. Just as with mercury, the formation of a metal-metal ...

    Periodic table of the chemical elements showing the most or more commonly named sets of elements (in periodic tables), and a traditional dividing line between metals and nonmetals. The f-block actually fits between groups 2 and 3; it is usually shown at the foot of the table to save horizontal space.

    The periodic table of the chemical elements.The columns represent the groups.Groups 1, 2 and 13 to 18 constitute the main group. Sometimes groups 3 and 12, as well as the lanthanides and actinides (the two rows at the bottom), are also included in the main group.

  8. 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.
