1 Nitrogen and Oxygen Family By Dana Wierzbicki, Lisa Malloy and Heather Hanlon

2 The Nitrogen Family N P As Sb Bi  All the elements in the Nitrogen Family have 5 electrons in there outermost energy level

3 Nitrogen Makes up 1/3 of the earths atmosphere It is a Non metal Nitrogen is used to protect historic documents It was discovered in Scotland in 1772 It dissolves in water and it is colorless

4 Phosphorus Discovered by Henning Brown in Germany, 1669 It can glowing the dark It its found in 85% of our bones Comes in 4 different forms: white, yellow, red and black These forms are used in fireworks, toothpaste, detergent, pesticides and more
