This is an 18-column periodic table layout, which has come to be referred to as the common or standard form, on account of its popularity. It is also sometimes referred to as the long form, in comparison to the short form or Mendeleev-style, which omits groups 3–12 by placing their elements into the main groups. The wide periodic table incorporates the lanthanides and the actinides, rather than separating them from the main body of the table in order to save space. The extended periodic table adds the 8th and 9th periods, including the superactinides.
