Bismuth has the lowest heat conductivity other than Mercury, and it is extremely resistant to electrical conductivity.
(Ian) Nitrogen, symbol N, this element was named nitrogen azote meaning without life, and discovered by Daniel Rutherford in 1772. Atomic number 7, atmoic mass 14.0067, melting point -209.86 celsius, boiling point -195.8 celsius, and its valence number is 5. It is the most abundant in the earth’s atmosphere. It had many uses such as four different kinds of explosives and everyday light bulbs plus the processing of iron and steel. Nitrogen is responsible for the colors of the aurora, it is orderless, tasteless, and colorless.

(Brandon) Element Name: Phosphorus Element Symbol: P Atomic Number: 15 Atomic Mass: 30.9 Discovered by: Hennig Brandt in 169 Melting Point: 44.15 Celsius Boiling: 280 Celsius Valence Number: +5 Location: Phosphate rock (Ca3)(PO4)2)
 * Phosphorous**

Phosphorus has many uses, it is used in fireworks, matches, and smoke bombs. Trisodium phosphate is used as cleaning detergent and water softener. Calcium phosphate is used for china and in production of baking powder. Some phosphorus compounds glow in the dark or emit light in response to radiation. Phosphorus is used to make certain types of protein. Phosphorus is also vital for the contraction of muscles, function of kidneys, maintain regularity of heart beat, and in nerve conduction.

 * Arsenic**

Element Name: Arsenic Element Symbol: As Atomic Number: 33 Atomic Mass: ~74.92 Melting Point: 817 Degrees Celsius Boiling Point: 614 Degrees Celsius Derivation: The Latin word arsenicum, and the Greek word arsenikon Discovered: 1250 Discovered By: Albertus Magnus

Arsenic is located 1.8 mg / 1 kg in the Earth's crust Arsenic is located 3.7-3 mg / liter in Earth's oceans

Usage: Insecticides, rat poison, transistors

Fun Facts:
 * Arsenic's melting point is higher than its boiling point, due to atmospheric pressure differences in which these are measured
 * The crystal structure of Arsenic is rhombohedral
 * Arsenic Oxide smells like garlic
 * Apple seeds contain arsenic
 * Arsenic is deadly to humans, although small doses are rumored to have beneficial effects
 * A tell-tale sign of Arsenic poisoning is thickening of the skin
