no. its in many compounds but not in many common materials.
Astatine is an extremely rare chemical element, not found in common materials.
Oxygen is an element and don'y contain any other element.
Any material that has Oxide in its name contains Oxygen. For example, RUST is Iron Oxide.
None! Xenon and oxygen are both elements, and by definition, no element contains any amount of any other element.
Oxygen is an element, not a reaction of any form.
No. It is a compound made of hydrogen and oxygen. An element is not made of any other elements.
What do you mean by A? The abbreviation, or any element. If so then try Oxygen or Nitrogen
Oxygen gas is not a change of any sort. It is an element.
Oxygen with the atomic mass given does not have any fixed number of neutrons because it is a mixture of isotopes. The most common isotope, oxygen-16, contains 8 neutrons per nucleus.
Carbon is actually the most common element in our body (in any living organism). Apart from carbon, oxygen, nitrogen and hydrogen are present in considerable amounts.
"Organic" materials are defined as materials that contain the element carbon, but a broader interpretation will include all of the CHON elements; Carbon, Hydrogen, Oxygen, and Nitrogen. Any substance that contains all four elements is certainly an "organic" molecule, even if it formed in the absence of any life process.
An "Oxidised Element" is any element that has reacted with Oxygen to form a compound. The compound suffixes of these compounds will be "Oxide, Monoxide, Dioxide, Trioxide" etc. Some examples of oxidised elements:Iron + Oxygen --> Iron OxideCarbon + Oxygen --> Carbon DioxideMagnesium + Oxygen --> Magnesium Oxide
