The reason why Helium is considered a noble gas is because its outermost (and at the same time only) shell is fully occupied by its 2 electrons.

International Union of Pure & Applied Chemistry: Commission on the Nomeclature of Inorganic Chemistry, Nomenclature of Inorganic Chemistry Recommendations 2005, Eds. Blocks in the periodic table should not be mixed up with groups (like noble gases).

In addition, groups may be idenitifed by the first element in each group - so the Group 16 elements is sometimes called the oxygen group.

Group 15: pnictogens (not an IUPAC approved name).

Group 11: coinage metals (not an IUPAC approved name).

The following names for specific groups in the periodic table are in common use: The second row of the f-block elements are called actanoids (or, less desirably, actanides). The first row of the f-block elements are called lanthanoids (or, less desirably, lanthanides). Include carbon, nitrogen, oxygen, sulfur, halogens, and many other common elements.

Main group elements in the first two rows of the table are called typical elements. This 20 piece block set is an interactive way to learn the names of the elements. Transition elements are those whose atoms have an incomplete d-subshell or whose cations have an incomplete d-subshell. Periodic table blocks are an ingredient list of the world around us. Groups 3-11 are termed transition elements. Groups 1-2 (except hydrogen) and 13-18 are termed main group elements.

If you do not see these colours, please upgrade your browser software. To see these colours, however, you need browser software with capable of shading the cells in a table. Elements in each block are colour coded in the background graphics, the periodic tables, and the element pages themselves. This gives the periodic table block in the standard periodic table in which the element is to be found.
