Hydrogen By molly schmidt
History The element of Hydrogen was discovered in 1766, by Henry Cavendish. He was the first to recognize the gas as a discrete substance. He recognized it by naming the gas from a metal acid reaction "Flammable air”. In 1671 a man named Robert Boyle discovered the reaction between iron filling and dilute acids, which results in the production of Hydrogen gas. How Hydrogen got its name was from the Greek words "hydro" and "genes", which together means "water forming".
