Oxygen: History and Occurrence
Credit for the discovery of oxygen is shared by two men, Joseph
Priestley, an English clergyman and amateur scientist, who later moved to
the United States to escape religious persecution, and Carl Wilhelm Schccle,
a Swedish pharmacist. Working independently, these two men both obtained
the gas which wc know as oxygen by heating various compounds of the
element, particularly mercuric oxide. They also found evidence that this
gas is a component of the atmosphere. Priestley’s work was published in
1774, but although Schcclc’s experiments had probably been performed
even earlier, their publication was delayed and no account of them appeared
*»Л
until 1777. Though Priestley recognized that the gas which he had
discovered plays an important role in combustion, he remained, along with
Schccle, an ardent adherent of the phlogiston theory of combustion; in
fact, he callcd the gas “dcphlogisticated air”.
On the basis of the experimental results o f Priestley, Schcelc, and
others, as well as some very fine experimental work of his own, in 1777
the brilliant French chcmist Lavoisier established the modem concept
that the combustion of a substancc consists in its combination with the
new gas which Priestley and Schcelc had described, and which Lavoisier
found an important constituent of the atmosphere. Sincc the combustion
of many substanccs (now known as non-metals) such as phosphorus and
sulphur yields products which react with water and give acidic solutions,
Lavoisier named this gas oxygen, derived from Greek words meaning
“acid former”.
Oxygen occurs in the free state as the second most abundant component
of the atmosphere; about one-fifth o f the air by volume is oxygen. In the
combined state it makes up 88.81% by weight of pure water, and, on the
average, 85.79% of sea water. It occurs in the earth’s crust, in the form of
a multitude of compounds, to the estimated extent o f46.43%.
