How Did Oxygen Get Its Name and Symbol: Acid!
The element oxygen received its name from the French word “oxygène,” which was coined in 1777 by the chemist Antoine-Laurent de Lavoisier.
“Oxygène” comes from the Greek words “oxys,” meaning “acid,” and “genes,” meaning “producer,” as oxygen was mistakenly believed to be essential to the formation of all acids.
The symbol ‘O’ for oxygen was adopted as a standard chemical symbol, representing the first letter of the element’s name and simplifying its representation in chemical formulas.
The naming and symbolism of oxygen are rooted in historical scientific discoveries and misconceptions.
The process involved:
Oxygen’s name reflects the era’s scientific understanding, marking a pivotal point in the history of chemistry.

The Discovery of Oxygen
The discovery of oxygen occurred in the late 18th century, leading to significant advancements in our understanding of chemical reactions and the composition of air.
It was first recognized as a distinct element by the Swedish chemist Carl Wilhelm Scheele in 1772 and independently by the British chemist Joseph Priestley in 1774.
Priestley’s work, in particular, paved the way for the modern understanding of oxygen. He isolated oxygen in its gaseous state and demonstrated its role in combustion and respiration.
This groundbreaking discovery revolutionized the field of chemistry, laying the foundation for Antoine Lavoisier’s subsequent identification of oxygen as an essential component in the process of combustion.
The discovery of oxygen was a pivotal moment in the history of science, fundamentally altering our understanding of chemical processes and the natural world.
The Naming of Oxygen
The naming of oxygen holds a significant place in the history of chemistry. It is intriguing to explore the origin of the name “oxygen” and the process through which its symbol “O” was discovered.
Understanding the historical and scientific context behind the naming of oxygen provides valuable insights into the development of chemical nomenclature and the contributions of early chemists to the field.
Origin of Oxygen Name
The origins of oxygen’s name can be traced back to the 18th century and the work of the chemist Carl Wilhelm Scheele. The naming of oxygen is attributed to the French chemist Antoine Lavoisier.
Lavoisier coined the term “oxygen” from the Greek words “oxy” and “genes,” which together mean “acid-forming.” This aptly describes oxygen’s role in the formation of acids.
The name “oxygen” replaced the earlier name “dephlogisticated air,” which was based on the outdated phlogiston theory.
Lavoisier’s naming of oxygen marked a significant shift in chemical nomenclature, emphasizing the importance of systematic and logical naming based on the element’s properties. The name “oxygen” has since become universally accepted and is used in various languages.
Oxygen Symbol Discovery
Having traced the origins of oxygen’s name back to the work of 18th-century chemists, the discovery of its symbol is equally noteworthy.
In 1772, Swedish chemist Carl Wilhelm Scheele first isolated oxygen, but it was the work of Joseph Priestley and Antoine Lavoisier that led to its recognition as an element.
Lavoisier’s 1787 publication, “Méthode de nomenclature chimique,” introduced the term “oxygen” derived from the Greek words for “acid-former.” The symbol for oxygen, “O,” was established based on its initial letter.
This standardized system of chemical symbols revolutionized scientific communication.
The table below illustrates the significance of the oxygen symbol discovery in the field of chemistry:
| Point of Emphasis | Importance |
|---|---|
| Standardized Symbol | Revolutionized scientific communication |
| Derived from Greek | Reflects its role as an acid-former |
| Simplified Chemical Notation | Enhanced clarity and precision |
