N - Nitrogen

The gas, nitrogen occupies 78 percent of our atmosphere, but it was not known until "mephitic air" was discovered by Daniel Rutherford in Scotland (and others, independently) in 1772. The inability of nitrogen to support combustion was the cause of its discovery and is explored by our students. Many compounds of nitrogen are also encountered.
