A university student in Northern England is the first to fall prey to the Student Slasher in this intricately constructed, stand-alone novel of suspense and revenge, originally published in the U.K. as Caedmon's Song.
Nitrogen is essential to life on Earth. It is a component of all proteins and it can be found in all living systems. Nitrogen compounds are present in organic materials, foods, fertilizers, explosives and poisons. Nitrogen is crucial to life, but in excess it can also be harmful to the environment.
nitrogen by itself is a diatomic molecule at STP (and pretty much in all conditions for that matter). This is so because Nitrogen has 5 valence electrons so each shares 3 electrons with the other. This gives each an unshared electron pair plus the 6 being shared between the two Nitrogen atoms.
