In its free state, oxygen is a gas without color, odor, or taste. It turns into a pale blue liquid at temperatures below –297° F (–183° C) and becomes solid at about –360° F (–218° C). Oxygen combines easily with many other elements to form substances called compounds.

Kids learn about the element oxygen and its chemistry including atomic weight, atom, uses, sources, name, and discovery. Plus properties and characteristics of oxygen.
Oxygen constitutes about two-thirds of the human body and nine-tenths (by weight) of the water in rivers, lakes, and oceans. In combination with other chemical elements, it forms hundreds of thousands of compounds, making up by weight almost half of the rock and sand in Earth’s crust.

6 dni temu · At standard temperature and pressure, oxygen has no colour, odour or taste and is a gas with the chemical formula O 2 called dioxygen. As dioxygen, two oxygen atoms are chemically bound to each other. This bond can be called many things, but simply called a covalent double bond. Dioxygen is very reactive and can react with many other elements.
Oxygen is an element with the chemical symbol O and atomic number 8. Oxygen is a very reactive element that easily forms compounds such as oxides. Under standard temperature and pressure conditions two oxygen atoms join to form dioxygen (O 2), a colorless, tasteless and odorless gas.
Oxygen is a gas with no color or smell. Humans and animals must breathe oxygen in order to live, and plants give off oxygen. Water (H 2 O) is a well-known chemical compound, which consists of one oxygen atom. Combustion, or burning, is caused by the reaction of oxygen and another element or compound.
