Pnictogen

The group 15 of the Periodic Table includes the naturally occurring elements nitrogen, phosphorus, arsenic, antimony and bismuth. The highly unstable in nature, not occurring transuranium Ununpentium, the sixth member of the group has already been repeatedly produced artificially. It is in both nitrogen and phosphorus non-metals, arsenic and antimony in order semimetals and bismuth is a metal.

The group is named after the first elements as nitrogen group or nitrogen -phosphorus group. The term Pentele (from gr πέντε pente = five ) is no longer recommended by the IUPAC, the term Pnicogene is not accepted.

The accepted by IUPAC, but uncommon term comes from the Greek word Pnictogene πνίγειν back, which means as much as asphyxiation.
