oxygen gas are indeed composed of molecules... ...molecules of O2 meaning every molecule of oxygen is usually two elemental oxygen atom put together
Nitrogen is the least abundant element in the atmosphere of the Earth. The most abundant element in the atmosphere of the Earth is oxygen.
oxygen
We might apply the term "molecular element" to an element that is not found as a single atom. Some examples might be in order to explain this.We often hear the term O2 applied to a gas in our atmosphere, which is the element oxygen. Oxygen is not generally found in the atmosphere in single atom units. It is found as diatomic molecules. We find that each oxygen atom has paired up with a "buddy" to form a "molecular element" and taken the form O2. Nitrogen, the most abundant gas in the atmosphere, also appears as the diatomic molecule N2.There are a few other elements that do not appear as "lone atoms" but will "hang around" with another atom of their kind. This is true of elemental gases, but not the inert or noble gases.
Oxygen is the most abundant element in Earth's crust.
Oxygen is the most abundant element in the Earth's crust, atmosphere, and oceans. It makes up about 46% of the Earth's crust by weight, about 21% of the atmosphere, and is a key component of water in the oceans.
The main element in the atmosphere is Nitrogen. The second is Oxygen.
The primary element in the atmosphere is nitrogen.
Ozone is not an element. It is a molecules. The molecule of ozone is formed by the combination of three oxygen atoms(where oxygen is an element).
Oxygen is the most common element in Earth's atmosphere after nitrogen.
Oxygen is found in the Earth's atmosphere, making up about 21% of the air we breathe. It is also found in water molecules (H2O), in the Earth's crust, and in living organisms as a key component of proteins, DNA, and other biological molecules.
Nitrogen, oxygen, argon
Nitrogen is the least abundant element in the atmosphere of the Earth. The most abundant element in the atmosphere of the Earth is oxygen.
oxygen
Oxygen is an atomic element. It is found in many molecules.
Oxygen is an atomic element. It is found in many molecules.
Oxygen can be found in the air we breathe, in water molecules (H2O), and in various organic and inorganic compounds. It is an essential element for life, as it is involved in key biological processes such as cellular respiration in organisms.
Oxygen is the third most abundant element in the universe and makes up about 21% of Earth's atmosphere by volume. It is a key component of many compounds essential for life, such as water and organic molecules.
