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.

He chose to call the element vanadin in Swedish (which has become vanadium in other languages including German and English) after the Old Norse Vanadís, another name for the Norse Vanr goddess Freyja, whose facets include connections to beauty and fertility, because of the many beautifully colored chemical compounds it produces.
