  2. Block (periodic table) - Wikipedia

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

    The group 12 elements zinc, cadmium, and mercury are sometimes regarded as main group, rather than transition group, because they are chemically and physically more similar to the p-block elements than the other d-block elements. The group 3 elements are occasionally considered main group elements due to their similarities to the s-block ...

  3. Main-group element - Wikipedia

    en.wikipedia.org/wiki/Main-group_element

    The s-block elements are primarily characterised by one main oxidation state, and the p-block elements, when they have multiple oxidation states, often have common oxidation states separated by two units. Main-group elements (with some of the lighter transition metals) are the most abundant elements on Earth, in the Solar System, and in the ...

  4. Periodic table - Wikipedia

    en.wikipedia.org/wiki/Periodic_table

    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.

  5. Chemical element - Wikipedia

    en.wikipedia.org/wiki/Chemical_element

    Block indicates the periodic table block for each element: red = s-block, yellow = p-block, blue = d-block, green = f-block. Group and period refer to an element's position in the periodic table. Group numbers here show the currently accepted numbering; for older numberings, see Group (periodic table) .

  6. Transition metal - Wikipedia

    en.wikipedia.org/wiki/Transition_metal

    In chemistry, a transition metal (or transition element) is a chemical element in the d-block of the periodic table (groups 3 to 12), though the elements of group 12 (and less often group 3) are sometimes excluded.

  7. Block Elements - Wikipedia

    en.wikipedia.org/wiki/Block_Elements

    Block Elements is a Unicode block containing square block symbols of various fill and shading. Used along with block elements are box-drawing characters , shade characters, and terminal graphic characters.

  8. Period (periodic table) - Wikipedia

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

    Period 4 includes the biologically essential elements potassium and calcium, and is the first period in the d-block with the lighter transition metals. These include iron , the heaviest element forged in main-sequence stars and a principal component of the Earth, as well as other important metals such as cobalt , nickel , and copper .

  9. Mercury (element) - Wikipedia

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

    A heavy, silvery d-block element, mercury is the only metallic element that is known to be liquid at standard temperature and pressure; [a] the only other element that is liquid under these conditions is the halogen bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature.
