Group+15



Tyler K. Elements in group 15

My elements are Nitrogen, Phosphorus, Arsenic, Antimony, Bismuth, and Ununpentium. The group's collective name is pnictogens and they all share one major characteristic, they all have 5 electrons in there outermost shell. They are also known for having high stability in compounds. Group 15 has two non-metals, two metalliods, one metal, and one synthetic.

1. //__**Nitrogen**__// Symbol: N Atomic Number: 7 Atomic Mass: 14.0067 Isotopes: N-13, N-14, N-15 Room temperature phase: Gas Freezing point (degrees Celsius): -210.00 Boiling point (degrees Celsius): -195.79 Conductivity: Does not Conduct Density: 1.251 g/liter at 0° C Solubility: Very low Solubility Ductility: Non-Ductible Malleability: Non-Malleable Who discovered: David Rutherford When discovered: 1772 Where discovered: Scotland



2. **//__Phosphorus__//** Symbol: P Atomic Number: 15 Atomic Mass: 30.973762 Isotopes: P-31, P-32, P-33 Room temperature phase: Solid Freezing point (degrees Celsius): 44.3 Boiling point (degrees Celsius): 280.5 Conductivity: Very Poor Conductivity Density: 1.82 g/cc At Solid State Solubility: Low Solubility Ductility: Average Ductility Malleability: Average Malleability Who discovered: Hennig Brand When discovered: 1669 Where discovered: Hamburg, Germany
 * Fun Fact:** Phosphorus was discovered by Hennig Brand who at the time was attempting to distill a Life Essence from his urine, and in the process produced a white material that glowed in the dark, which turned out to be Phosphorus.

3. **//__Arsenic__//** Symbol: As Atomic Number: 33 Atomic Mass: 74.92 Isotopes: As-73, As-74, As-75 Room temperature phase: Solid Freezing point (degrees Celsius): 808 Boiling point (degrees Celsius): 603 Conductivity: Poor Conductivity Uses: Poison, Pesticides, Wood Preservative, Calcium arsenate(Ca3(AsO4)2) use to be used as a very powerful Pesticide Flammability: Rarely Flammable Toxicity: Very Toxic Chemical stability: Stable under ordinary conditions Reactivity With Oxygen: Diarsenic trioxide, Diarsenic pentoxide General Reactivity: Low Reactivity Density: Largely Varies From Form to Form Solubility: Insoluble Ductility: Low ductility Malleability: Easy Malleability
 * Fun Facts:** Arsenic has been used as poison since ancient times. Since its been used by the ruling class to kill one another so often, it has been given the such nicknames as The Poison of Kings and, The King of Poisons.



4. **//__Antimony__//** Symbol: Sb Atomic Number: 51 Atomic Mass: 121.760 Isotopes: Sb-121, Sb-123, Sb-125 Flammability: Flammable Toxicity: Toxic Reactivity With Oxygen: Diantimony trioxide, Diantimony tetroxide, Diantimony pentoxide Chemical stability: Stable under ordinary conditions General Reactivity: Average Reactivity Uses: batteries, antifriction alloys, type metal, small arms and tracer bullets, cable sheathing. Sb2O3 (Antimony trioxide) is used as a pigment and a Flame retardant
 * Fun Facts:** In Biblical times Antimony was used as a Medicine and cosmetic. The Muslim prophet Muhammad once said, "Among the best types of collyrium is antimony for it clears the vision and makes the hair sprout."



5. //__**Bismuth**__// Symbol: Bi Atomic Number: 83 Atomic Mass: 208.9804 Isotopes: Bi-207, Bi-208, Bi-209, Bi-210 Flammability: Flammable Toxicity: Low Toxicity Reactivity With Oxygen: Dibismuth trioxide Chemical stability: Stable under ordinary conditions General Reactivity: Low Reactivity, Works well with Halogens Uses: used in producing malleable irons, as a catalyst for making acrylic fibres, the metal is used as a thermocouple material, carrier for uranium fuel in nuclear reactors, fire detection, extinguishing systems, cosmetics, medicine, Bismuth germanate(Bi12GeO20) is used in Detectors

6. **//__Ununpentium__//** Symbol: Uup Atomic Number: 115 Atomic Mass: Undetermined, common guess is 288 Isotopes: Uup-287, Uup-288 Who discovered: Joint Institute for Nuclear Research, and scientists at the Lawrence Livermore National Laboratory When discovered: February 2, 2004 Where discovered: Dubna, Russia, and Lawrence Livermore National Laboratory in America
