Look at the air around you- do you see anything? About 80% of that air is nitrogen. As a gas, it has no color, no shape. Nothing to see here. Move along.
It is very complicated.
you cant see an atom!
yes, if you look at a picture of mars, you will see a thin layer of what looks like cloud but is actually nitrogen.
There is more than one step in nitrogen fixation but it can be seen as a flash of lightning heating the atmosphere, or in certain plants such as clover or alder.
Pluto's interior is made up of nitrogen, carbon monoxide ,and methane.
nitrogen fixation. look it up
Plants do not technically need nitrogen to survive, infact they need "Carbon Dioxide" Co2, but as Nitrogen makes up most of atmosphere (approx 95%) but they do need it for the color of the leaves and contains nutrients. Here is a link to a picture of what It looks like without nitrogen: http://www.progressivegardens.com/growers_guide/nitrogen.jpg
look for nitrogen, if it has nitrogen it's likely a enzyme
Arsenic belongs to the nitrogen family, also known as Group 15 elements on the periodic table.
Deficiency of nitrogen gives pale yellow color to the plant
A nitrogen particle is composed of one nitrogen atom. At the atomic level, nitrogen atoms have a dense nucleus surrounded by a cloud of electrons, giving them a spherical shape. Nitrogen atoms typically form diatomic molecules (N2) under normal conditions due to their tendency to bond with another nitrogen atom through a triple covalent bond.
It doesn't. Nitrogen is odorless.
