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.
Oxygen combined with one other element is an oxide.
Oxygen is an element in its own right, so it only contains one element: oxygen.
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.
Nitrogen is not in oxygen; they are separate elements. Nitrogen is a different element with its own properties, and it makes up around 78% of the Earth's atmosphere. Oxygen, on the other hand, makes up about 21% of the atmosphere and is crucial for respiration in living organisms.
No because Oxygen is an element and it only contains atoms of Oxygen and nothing else, no Hydrogen at all. A compound of Hydrogen must contain Hydrogen plus something else. Water contains Hydrogen and Oxygen (H2O) so that would be a compound of Hydrogen and oxygen.
only oxygen is a gas :)
Oxygen is an element and don'y contain any other 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.
Sand is a mixture of different elements (such as silicon, oxygen, and others) and is not considered an element on its own. Iron, on the other hand, is an element with the symbol Fe on the periodic table.
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.
It is not one single element, but several.
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.
