"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.

∙ 11y agoOxygen is an element and is found in the forms O2 and O3 as molecules. They are not, however, compounds since it is made entirely of oxygen. A chemical is just a generic word for anything that is made up of elements no matter what it may be. A compound is a molecule made up of more than one element, such as carbon dioxide, CO2.

A chemical compound consists of two or more different chemical elements.

∙ 13y agoCompounds are formed when 2 or more different element bond together.
In oxygen molecule, there is only 1 kind of element (i.e. Oxygen) thus is a molecule of element.

What are Oxygen nitrogen and hydrogen examples of?
Oxygen and carbon are examples of atoms. Water is an example of a "molecule" because it is made up of two hydrogens atoms and an oxygen atom.
How many oxygen atoms are in 6 molecules of water?
6 atoms of oxygen are present. Three O2 contains 6 O atoms.
What are molecules consisting of carbon hydrogen and oxygen?
Such compounds are called "carbohydrates", if they contain hydrogen atoms and oxygen atoms in an atomic ratio of 2:1, as most compounds containing only the three specified elements do.
How many atoms of O are in 3Na2SO4?
Na2SO4
How compounds and molecules are related to elements and atoms?
Atoms are the smallest units of an element into which that element can be divided. And atoms are the building blocks of molecules. Compounds are just that - something that is compounded or has two or more elements combined to make it up. Atoms are the building blocks of compounds. An atom of one element that combines with an atom of another element creates a compound, a molecule of that compound. A compound is made up of molecules, and they can be simple two-atom molecules or can be molecules that are dozens or hundreds of atoms in size.
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).
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.
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.
Why are all compounds molecules?
All compounds are made up of molecules. For example, salt, a compound, is composed of molecules (NaCl). By please do remember that molecules are not only limited to compounds. Meaning, there are also molecules that are not classified as compounds. The definition of a compound is a substance that is made up of two or more elements. A molecule is composed of two or more ATOMS connected by chemical forces. An example is oxygen air (O2). Oxygen air is a diatomic MOLECULE but it is NOT a COMPOUND.
What is the relationship of a molecule and an atom?
Molecules are composed of atoms. Atoms are to elements as molecules are to compounds.
Atoms and molecules of different elements can do what to form molecules of compounds?
(Two or more than two ) Atoms or molecules of different elements combine to form compounds, like: Hydrogen(atom) and Chlorine combine to form HCL (an acid) Hydrogen(molecule) and oxygen combine to fom H2O (water)
Can molecules be compounds?
A compound is a substance in which two or more elements are bonded together chemically. There are some molecules, such as oxygen, O2, that consist of two or more atoms of the same element. Apart from these, all molecules are compounds. Please see the link.
How many atoms does a carbohydrate have?
Carbohydrate molecules are compounds of carbon, hydrogen, and oxygen atoms in various proportions.
Why compounds are molecules?
