What is the purpose of researching elements on the periodic table?

he number of protons give elements their unique chemical properties, and define their electron energy levels. All three of these elements are naturally occurring, and act chemically like hydrogen because they each have one proton. The different number of neutrons gives them all greatly different atomic mass.

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .
