Hydrogen: The First Element

Cosmic Formation

Gary Arndt explores hydrogen's formation and its cosmic abundance. He explains that hydrogen, the simplest atom with one proton and one electron, was the first element formed after the Big Bang. This element constitutes 98% of observable matter, including stars and interstellar gas clouds 1. Hydrogen's lightness allows it to escape Earth's atmosphere, making it rare in its native form here 2.

Hydrogen is the vast majority of everything we can see in the universe. 98 point of all baryonic matter, that is the stuff that we are familiar with, not dark matter, is hydrogen.

Despite its abundance, hydrogen's presence on Earth is mostly in compound forms like water, due to its tendency to bind with other elements.

   

Discovery Journey

The discovery of hydrogen was a gradual process, beginning with Robert Boyle in 1671, who first identified a gas produced from iron filings and acids. Henry Cavendish later recognized it as a unique gas in 1766, naming it "inflammable air" and discovering its combustion produced water 3. The term "hydrogen" was coined by Antoine Lavoisier in 1788, derived from Greek words meaning "coming from water."

The name hydrogen was coined by the french chemist Antoine Lavoisier in 1788. The word comes from the greek words hydro and gens, which just means coming from water.

Hydrogen's buoyancy was first utilized in 1783 with the launch of a hydrogen balloon, marking the beginning of its use in air travel.
