  1. Group 15, the Nitrogen Group

  2. Representative Elements Group 15—The Nitrogen Group • Nitrogen and phosphorus are required by living things and are used to manufacture various items. • These elements also are parts of the biological materials that store genetic information and energy in living organisms.

  3. Representative Elements Group 15—The Nitrogen Group • Although almost 80 percent of the air you breathe is nitrogen, you can’t get the nitrogen your body needs by breathing nitrogen gas. • Bacteria in the soil must first change nitrogen gas into substances that can be absorbed through the roots of plants. • Then, by eating some plants, nitrogen becomes available to your body.

  4. Representative Elements Group 15—The Nitrogen Group • Ammonia is a gas that contains nitrogen and hydrogen. • When ammonia is dissolved in water, it can be used as a cleaner and disinfectant. • Ammonia also can be converted into solid fertilizers. • It also is used to freeze-dry food and as a refrigerant.

  5. Representative Elements Group 15—The Nitrogen Group • The element phosphorus comes in two forms—white and red. • White phosphorus is so active it can’t be exposed to oxygen in the air or it will burst into flames. • The heads of matches contain the less active red phosphorus, which ignites from the heat produced by friction when the match is struck.

  6. Representative Elements Group 15—The Nitrogen Group • Phosphorous compounds are essential ingredients for healthy teeth and bones. • Plants also need phosphorus, so it is one of the nutrients in most fertilizers.
