The fact that it allows us the breath is a big one. There are also other reasons like it's molecular structure and it's position on the Periodic Table. Oxygen was one of the first elements on the planet, which suggests organice life. This alone makes Oxygen a a fundamental part of our lives. It holds the value of life, and GIVES us life. Without it, we would be dead.
It is air we breath
Oxygen combined with one other element is an oxide.
Oxygen is an element in its own right, so it only contains one element: oxygen.
The basic element of living species is Carbon other are hydrogen and oxygen.
nitrogen
No, they are different forms of the same element, so they are allotropes. Oxygen contains two atoms per molecule and ozone contains three atoms per molecule. Isotopes are atoms of the same element with different numbers of neutrons, such as oxygen-16 and oxygen-17.
only oxygen is a gas :)
Oxygen is an element and don'y contain any other element.
It is the same for each and every element, it's the number of protons in the nucleus of one atom of the element.
Oxygen has 8 neutrons. However, there are other isotopes that have a different number than this.
Special chemical reactions such as hydrogen bonding.
Oxygen combined with one other element is an oxide.
Oxygen is not a mixture, it is a pure element. Air, however, is a mixture of many different elements. In other words, oxygen only has oxygen in it. Air has oxygen, nitrogen, carbon, hydrogen, and other elements in it.
Oxygen is an element and is not composed of other elements.
Oxygen is an element - it contains no other constituent gases.
its an element. It is usually encountered as O2. There are other allotropic forms the best known is O3 ozone.
No. It is a compound made of hydrogen and oxygen. An element is not made of any other elements.
No. They are two different elements.
