"A chemical compound is a pure chemical substance consisting of two or more different chemical elements"
So says wikipedia!
O2 does not have two or more different chemical elements and so cannot be a compound. It is, however, a molecule (which only requires 2 or more atoms connected by bonds).
To clarify - all compounds are molecules...but not all molecules are compounds.
O2 represents a molecule of oxygen.
An atom is the smallest component of any element having all the chemical properties of that specific element.
A molecule is the simplest complete structural unit of an element or compound that can exist in nature.
A compound is a substance consisting of two or more different elements or molecules formed by the chemical union of two or more elements or molecules in definite proportion by weight.

What are examples of oxygen?
Examples of oxygen include the oxygen gas we breathe in the atmosphere, oxygen molecules in water (H2O), and oxygen atoms in organic compounds like carbohydrates and fats.
Do compounds always contain different types of atoms?
No, compounds can contain the same type of atoms bonded together. These are called diatomic molecules, such as oxygen gas (O2) or nitrogen gas (N2), where two atoms of the same element are chemically bonded.
How many oxygen atoms are in 6 molecules of water?
6 atoms of oxygen are present. Three O2 contains 6 O atoms.
Are molecules always compounds?
A molecule is formed when two or more atoms join together. And a compound is a molecule that contains at least two different elements. So all compounds are molecules but not all molecules are compounds.
What causes the formation of nitrogen compounds and ozone?
Excess energy (energetic light or energetic electrons) will break apart an oxygen molecule, forming two oxygen atoms. Likewise, nitrogen molecules are also broken apart into nitrogen atoms. Those oxygen and nitrogen atoms will recombine in most cases, making hot oxygen and nitrogen. But in non-zero percentages, ozone, nitrous oxide, nitrogen oxide, and even more complex assemblies are the result. Not all reactions return to their lowest level in the first step. Sometimes "free radicals" are the result.
How can all compounds be molecules but not all molecules compounds?
All compounds are molecules because they are made up of two or more atoms chemically bonded together. However, not all molecules are compounds; for example, an element like oxygen gas (O2) consists of molecules made up of two oxygen atoms but does not contain different elements bonded together like a compound does.
What happens to oxygen when hydrogen is removed from h2o?
When hydrogen is removed from H2O, oxygen atoms remain. These oxygen atoms may bond with other atoms to form new compounds or molecules, such as O2 (oxygen gas) or H2O2 (hydrogen peroxide), depending on the conditions.
Are elements and compounds are made of atoms?
Yes. Elements are composed of individual atoms. Compounds are composed of molecules, which are chemical combinations of atoms. Some pure elements exist as molecules containing various numbers of combined atoms, such as atmospheric oxygen (O2) and ozone (O3).
Are molecules only found in compounds?
No, molecules can exist both in compounds and as individual elements. In compounds, molecules are formed when atoms chemically bond together. In the case of elements, some exist as diatomic molecules (like oxygen, O2), while others exist as single atoms (like helium, He).
What do atoms fuse to form into?
Atoms can fuse together to form molecules or compounds.
Are molecules samller then atoms?
No, they are compounds of atoms
Are elements and compounds made of atom?
Yes. Elements are composed of individual atoms. Compounds are composed of molecules, which are chemical combinations of atoms. Some pure elements exist as molecules containing various numbers of combined atoms, such as atmospheric oxygen (O2) and ozone (O3).
What are the total number of atoms in two oxygen molecules?
There are 4 oxygen atoms in two oxygen molecules.
How many oxygen atoms are there in dioxide molecules?
There are 2 oxygen atoms in dioxide
Are atoms a compound?
Atoms are elements, not compounds. Compounds are composed of two or more different atoms. For example, the element carbon, with the symbol C, is composed of atoms. If you combine carbon and oxygen to make carbon dioxide (CO2) then you have a compound, composed of molecules, each of which have 3 atoms, one carbon and two oxygen.
What are examples of oxygen?
Examples of oxygen include the oxygen gas we breathe in the atmosphere, oxygen molecules in water (H2O), and oxygen atoms in organic compounds like carbohydrates and fats.
What compounds form molecules?
Compounds are made of molecules that are composed of two or more atoms chemically bonded together. The atoms can be the same element (such as O2 for oxygen) or different elements (such as H2O for water). The type and arrangement of atoms in a molecule determine its properties.
