Group 15 / VA; Nitrogen Group

Nitrogen (N) and phosphorous (P) are part of all biology and thus also of organic chemistry.
Phosphorous and arsenic (As) are very important for doping silicon, and nitrogen is found in many ceramics. There are also many applications of arsenic or its oxide (As2O3) in mystery books.
Bismuth is used in some high-tech products (like thermoelectric generators or Peltier elements): it's and antimony's (Sb) hey-days are yet to come.
