P9+-+Nitrogen


 * __The Nitrogen Group__ By Steffi Bauer and Erin Calamari **

The group of Nitrogen is 15. The period for Nitrogen is 2-6.

Nitrogen is the only element in the Nitrogen group that is a gas at room temperature. The rest of the group, Phosphorus, Arsenic, Antimony, and Bismuth are all solids at room temperature.

The five elements of the Nitrogen group, also known as Group 15, are:

Nitrogen

Phosphorus 15

Arsenic 33

Antimony 51

Bismuth 83

** __Chemical Properties:__ ** __Physical Properties:__ ** __Interesting Facts: __ **
 * 1) Nitrogen only reacts at room temperature with lithium.
 * 2) Phosphorus reacts with metals to form phosphides.
 * 3) Some micro-organisms react directly with nitrogen gas, called Nitrogen Fixation, to build protein.
 * 1) All the elements have five electrons.
 * 2) Nitrogen is colorless and odorless.
 * 3) Bismuth expands when it freezes.
 * 1) Another name for the nitrogen group is Pnictogens.
 * 2) The element nitrogen makes up 78% of the Earth's air.
 * 3) There are two types of Phosphorus, White Phosphorus and Red Phosphorus.
 * 4) Arsenic, Antimony, and Bismuth are mostly found in minerals.

** __Common Uses:__ **
 * 1) Nitrogen is used for breathing.
 * 2) Nitrogen is found in fertilizers.
 * 3) Phosphorus is used in matches.
 * 4) Arsenic is used to create harder and rounder bullets.
