Block (periodic Table) - Periodic Table

Periodic Table

Helium is placed next to hydrogen instead of on top of neon because it is part of the s2 group. In addition to the blocks listed in this table, there is a hypothetical g-block which is not pictured here. g-block elements can be seen in the expanded extended periodic table. Also, lutetium and lawrencium are placed under scandium and yttrium to reflect their status as d-block elements.

Famous quotes containing the words periodic and/or table:

    “It can be demonstrated that the child’s contact with the real world is strengthened by his periodic excursions into fantasy. It becomes easier to tolerate the frustrations of the real world and to accede to the demands of reality if one can restore himself at intervals in a world where the deepest wishes can achieve imaginary gratification.”
    —Selma H. Fraiberg (20th century)

    “... So damn your food and damn your wines,
    Your twisted loaves and twisting vines,
    Your table d’hôte, your à la carte,
    . . . .
    From now on you can keep the lot.
    Take every single thing you’ve got,
    Your land, your wealth, your men, your dames,
    Your dream of independent power,
    And dear old Konrad Adenauer,
    And stick them up your Eiffel Tower.”
    —Anthony Jay (b. 1930)
