Who named oxygen?

According to the Royal Society of Chemistry, the element oxygen was named by Antoine Lavoisier in 1777, although he was not the first to discover it. The term means "acid forming," since it was thought at the time that oxygen was required for the production of any acid.

The discovery of oxygen was done by three different people within a few years of each other and unknown to the other two. The first to experiment with the element was Carl Wilhelm Scheele in 1771. Another scientist, Joseph Priestley, also made the discovery and was the first to publish his findings in 1774.
