Nitrogen

Element Name: Nitrogen. Origin: from the greek words 'nitron genes' meaning 'nitre' and 'forming' Symbol: N Atomic Number: 7Atomic Mass: 14.007Number of electrons: 7Number of protons: 7Number of Neutrons: 7

Nitrogen was discovered in Edinburgh, Scotland by scottish physican and chemist, Daniel Rutherford in 1772. I chose to write about nitrogen because nitrogen seemed like an interesting topic to write about. Most of the air we breathe is mostly nitrogen, so i thought it would be pretty interesting to know excatly what nitrogen does for us, and some more imformation about it.

Nitrogen is found in everything around us. Such as ammonia. Ammonia is used in disinfectant products because it kills bacteria and fungus. Nitrogen is also used as a refrigerant, because when nitrogen is liquid it can be used to freeze things.Some health affects that nitrogen has is: -It decreases functioning of thyroid glands.-Vitamin A shortages

About Nitrogen

If nitrogen was removed from the air everyone would die because life today is suited for our current atmosphere (78% nitrogen, 21% oxygen, 1% argon. Some environemntal concerns that nitrogen brings to earth is: pollution to aquatic ecosystems. ( When too much nitrogen and phosphorus enter the water, causing growth of algae and aquatic) Reduced crop, forest and grassland productivity due to nitrogen deposition (build up of nitrogen) Production of green house gases.

Environmental Concerns

Tasteless, odourless, colourless gas.Melting Point: -210.1˚C (-320.45˚F)Boiling Point: -195.8˚C (-346.02 ˚F)Density: 1.251g/lFifth most abundant element on earth.

Room Temperature: Very inactive gasDoes not combine with oxygen or hydrogen and other elements.Does combine with oxygen in the presence of lightning or a spark. The electrical energy from either causes nitrogen and oxygen to form into nitric oxide, which is a more active gas than free nitrogen. Changing the element into different compounds is called nitrogen fixation. Plants have different ways of fixing nitrogen, the bacteria lives on the root hairs of plants. They take the air dissolved into the ground and convert it into compounds called nitrates. Plants grow because the bacteria fixes the nitrogen for them. they use the nitrogen to make protein for them. So people and animals survive because they eat plants. All living organisms depend on soil bacteria to fix their nitrogen form them, in order to survive.

Reactions

Reacts with group 1: alkali metals ( Li, Na, K, Rb, Cs, Fr) Lithium is the only element to react with nitrogen gas at room temperature.Group 2: Alkaline Earth Metals ( Be, Mg, Ca,Sr, Br)Reacts with nitrogen, has a required amount of heat.Reacts with main group 13-18 elementsMain elements (B, Al,Ga,In,Si, Ge,P) Are the only elements to react with nitrogen making their appropriate binary nitrides. Binary nitride: binary compound of nitrogen with a more electropositive element.
