When a molecule is formed of different elements, it is called a compound. Examples of molecules are: O2 – a simple molecule comprising two atoms of oxygen. N2 – a simple molecule comprising two atoms of nitrogen.
O2 represents a molecule of oxygen which is made up of two atoms of oxygen ;compounds are composed of different types of elements for example HO. Thus,O is an element.
O2 is a molecule but it is not a compound for the same reason. H2O is both a molecule (because it is composed of two atoms) and it is also a molecule (because there are two different types of element involved; hydrogen and oxygen).
Oxygen is the chemical element with the symbol O and atomic number 8. … At standard temperature and pressure, two atoms of the element bind to form dioxygen, a colorless and odorless diatomic gas with the formula O2.
The difference between oxygen (O) and oxygen (O2 )is that the former is an oxygen atom while the latter consists of two O atoms bound together, forming a molecule also called oxygen. Oxygen is usually found as a diatomic gas. Therefore, we write it as O2.
oxygen (O), nonmetallic chemical element of Group 16 (VIa, or the oxygen group) of the periodic table.
Where did oxygen get its name? The name oxygen comes from the Greek word “oxygenes” meaning “acid producer”. It was called this because early chemists thought that oxygen was necessary for all acids. There are three stable isotopes of oxygen.
Carbon dioxide (CO2) is an odorless, colorless gas. It is a waste product made by your body.
Atoms that share electrons in a chemical bond have covalent bonds. An oxygen molecule (O2) is a good example of a molecule with a covalent bond. Ionic bonds occur when electrons are donated from one atom to another. Table salt (NaCl) is a common example of a compound with an ionic bond.
Carbon dioxide is a molecule with the molecular formula CO2. Carbon dioxide, CO2, is a colorless gas. It is made of two oxygen atoms covalently bonded to one carbon atom. It is exhaled by animals and utilized by plants during photosynthesis. Carbon dioxide: It is a colorless and odorless molecule.

Ozone: Ozone, O3, is a molecule that is composed of three oxygen atoms. Stratospheric ozone protects organisms from harmful ultraviolet light, while tropospheric ozone is regarded as a pollutant.
Oxygen in the atmosphere is a molecule because it contains molecular bonds. It is not a compound because it is made from atoms of only one element – oxygen. This type of molecule is called a diatomic molecule, a molecule made from two atoms of the same type.
In a covalent bond, electrons are shared between two atoms. When twooxygen atoms bond together to form an oxygen molecule, they share four electrons – two from each oxygen atom.
So, to reiterate, the difference between oxygen (O) and oxygen (O2) is that the former is an oxygen atom while the latter consists of two O atoms bound together, forming a molecule also called oxygen.
Sulfur dioxide/IUPAC ID

Oxygen is a non-metal element and is found naturally as a molecule. Each molecule is made up of two oxygen atoms that are strongly joined together. Oxygen has low melting and boiling points, so it is in a gas state at room temperature.
Oxygen, carbon, sulfur and chlorine are examples of non-metal elements. Non-metals have properties in common.
The name oxygen was coined in 1777 by Antoine Lavoisier, who first recognized oxygen as a chemical element and correctly characterized the role it plays in combustion.
This element is colorless, odorless, and tasteless. That means even though oxygen is constantly around you, you can’t see it, smell it, or taste it. What is this? Every time you take a breath, you are breathing in oxygen, and you need oxygen to live.
Air is nothing but a mixture of a variety of gasses. The air in the atmosphere consists of nitrogen, oxygen, which is the life-sustaining substance for animals and humans, carbon dioxide, water vapour and small amounts of other elements (argon, neon, etc.).
How much carbon is released from Dry Ice? One pound of dry ice will produce about 8.3 cubic feet of carbon dioxide. Approximately 4-1/2 lbs. of liquid CO2 will yield one pound of dry ice.
Carbon is a chemical element with symbol C and atomic number 6. Classified as a nonmetal, Carbon is a solid at room temperature.
A) Carbon dioxide in exhaled breath is a matter as it has a mass and it occupies a volume.
oxygen molecule is O2 composed of two identical oxygen atom so it will be covalent. N2 (nitrogen molecule), Cl2 (chlorine molecule), Br2 (Bromine molecule) are also diatomic homonuclear molecules so they are all covalent.
