Etymology

HN comes from the two chemical symbols H and N, which stand for hydrogen and nitrogen, so the name is simply those elements together and easy to remember, like H2O ('water'). That's why HN refers to a very simple but unstable chemical made of those elements, which helps explain why it can be poisonous, smelly and explosive.
