Question
How did the name ‘hydrogen’ originate? How does hydrogen occur in the combined state?
Solution
At first, hydrogen was referred to as an "inflammable gas." It burned in the atmosphere, creating water. Lavoisier gave it the name "hydrogen," which means "water producer," in 1783. [Greek word Hydro = water, gen = producer]
Hydrogen occurs in the combined state:
- Compounds containing hydrogen, along with carbon, oxygen, and nitrogen, make up plant and animal tissues.
- Hydrogen makes up around one-ninth of the mass of water.
- as an ingredient in various substances, such as organic compounds, petroleum products, acids, and alkalis.
