Facts about the
Definition of the Element Oxygen
A colorless tasteless odourless gaseous element that constitutes
21 percent of the atmosphere and is found in water, in most rocks
and minerals, and in numerous organic compounds, that is capable
of combining with all elements except the inert gases, that is
active in physiological processes, and that is involved especially
in combustion processes. The most common uses of Oxygen are
in Oxidizer, Rocket propulsion, Medicine, Welding, Sensors, Mask
and Concentrators
Interesting Facts
about the Origin and Meaning of the element name Oxygen
What are the origins of the word Oxygen ?
The name originates from the Greek words gennan meaning 'generate'
and oxus meaning 'acid' - so named because it was believed that
all acids contained oxygen.
Facts about the
Classification of the Element Oxygen
Oxygen is classified as an element in the 'Non-metals' section
which can be located in groups 14,15 and 16 of the Periodic Table.
Non-metals are not easily able to conduct electricity or heat and
do not reflect light . Non-metallic elements are very brittle, and
cannot be rolled into wires or pounded into sheets. Non-metallic
elements exist, at room temperature, in two of the three states of
matter : gases (such as oxygen) and solids (such as carbon).
Brief Facts about the
Discovery and History of the Element Oxygen Oxygen was discovered by Carl
Wilhelm Scheele in Sweden in 1771 and then by Joseph Priestley in
1774. It was named by Antoine Laurent Lavoisier in 1774.

Facts and Info about
the element Argon - IUPAC and the Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the
International Union of Pure Applied Chemistry, IUPAC, in 1985
which includes the Oxygen element. The famous Russian Scientist,
Dimitri Mendeleev, perceived the correct classification method of
"the periodic table" for the 65 elements which were known in his
time. Oxygen was discovered by Carl Wilhelm Scheele in Sweden in
1771 and then by Joseph Priestley in 1774. It was named by Antoine
Laurent Lavoisier in 1774. The Standardised Periodic Table now recognises more periods
and elements than Dimitri Mendeleev knew in his day but still all
fitting into his concept of the "Periodic Table" in which
Oxygen is
just one element that can be found.
