At lower temperatures and higher pressures, oxygen changes its appearance from blue monoclinic crystals to orange, red, black, and even a metallic appearance. Oxygen is a non-metal
Oxygen (O) is a chemical element. Oxygen is a diatomic molecule, meaning it consists of two O atoms bonded together chemically. O is its official chemical symbol, while 8 is its atomic number. This means that an oxygen atom contains 8 protons and 8 electrons in its nucleus is oxygen gas an element or molecule. i am thinking it is a molecule, not an element, mixture or compound. mixture is obvious, not a compound cause it only has one atom in it, and it isnt an element cause it can br broken down. (eg heating Hg in presence of oxygen gas causes HgO to form....oxygen atoms have been seperated) but i have found many sources saying that oxygen/nitrogen gas are.

Hydrogen gas is the lightest and simplest element and, with a ratio of 80%, is the main ingredient of the visible universe. the other 20% consist of helium, the ratio of the heavier elements is below 1%. Most stars, including our Sun, generate energy by the fusion of hydrogen gas with helium gas oxygen. . gaseous chemical element, 1790, from French oxygène, coined in 1777 by French chemist Antoine-Laurent Lavoisier (1743-1794), from Greek oxys sharp, acid (from PIE root *ak-be sharp, rise (out) to a point, pierce) + French -gène something that produces (from Greek -genes formation, creation; see -gen).. Intended to mean acidifying (principle), it was a Greeking of French. Bi mass, oxygen is the third-maist abundant element in the universe, efter hydrogen an helium.

Located at Group 6 and Period 2 is the essential gas for us to stay alive. This is Oxygen. First , Discovered by Carl Wilhelm Scheele in 1772.But named by Antoine Lavosier
Oxygen definition, a colorless, odorless, gaseous element constituting about one-fifth of the volume of the atmosphere and present in a combined state in nature. It is the supporter of combustion in air and was the standard of atomic, combining, and molecular weights until 1961, when carbon 12 became the new standard. Symbol: O; atomic weight: 15.9994; atomic number: 8; density: 1.4290 grams. Lavoisier was the first person to declare that the new gas was an element. He was also the first person to explain how oxygen is involved in burning. In addition, he suggested a name for the gas. That name, oxygen, comes from Greek words that mean acidic (oxy-) and forming (-gen) In a series of experiments culminating in 1774, Priestley found that air is not an elementary substance, but a composition, or mixture, of gases. Among them was the colorless and highly reactive gas he called dephlogisticated air, to which the great French chemist Antoine Lavoisier would soon give the name oxygen Oxygen makes up nearly half of the Earth's crust mass and 86% of the mass of the Ocean. That alone makes it a very important element. Then we add the fact that we need it to breathe, and we see the importance of oxygen. On Earth the production of oxygen gas (also called elemental oxygen) comes from photosynthesis carried out by plants and algae
