What Are The Examples Of Molecules? 

There are multiple examples of molecules. Today we will understand them in detail and also add some more examples to it. Learning about molecules will be interesting because molecules are everywhere, from the air you breathe to the sugar making those cookies so sweet. But, the important thing is that we usually pay little attention to it. By reading this article, you will pay attention to it. During your schooling, you learned many terms and their definitions like atoms, compounds, elements, and even molecules. But, here we will learn by making them simple and easy to understand. Let’s have a look at some examples of molecules

What Are The Molecules?  

Before learning the examples of small molecules the big concern you readers have may be what is molecule. Let’s have a look at the molecule definition. A molecule is defined as an electrically neutral group of two or more atoms connected by chemical bonds. People got confused about some basic terms like atom, compound, and molecules. 

Well, the atom is a small or tiny particle of matter that characterizes a chemical element. It is a tiny particle in ordinary matter. While the compound is a substance that is made up of two or more different elements that are chemically joined and they are like water, carbon dioxide, sodium chloride, etc. Lastly, molecules are electrically neutral groups of two or more atoms connected by chemical bonds. 

Let’s have a look at some common molecules in everyday life

What Are The Examples Of Molecules?  

Here are some examples of molecules that may encourage you to pay attention to different molecules around you. 

  1. Water 
  2. Nitrogen 
  3. Ozone 
  4. Calcium Oxide 
  5. Carbon Dioxide 
  6. Glucose And All Types of Sugar 
  7. Table Salt 
  8. Haemoglobin  
  9. Vitamin C 
  10. Deoxyribonucleic Acid   

Examples Of Molecules  

There are more than 50 examples of molecules because everything on the planet is made of molecules. Because molecules are nothing but a combination of atoms. Let’s understand some important examples of molecules of elements. 

1. Water 

One of the simple molecule examples is Water and its chemical formula is H2O. in water, there are two components of hydrogen and one atom of oxygen. It is a tiny molecule in which hydrogen and oxygen atoms cling to each other because of a force called hydrogen bonding. It is the reason why water can do amazing things. 

2. Nitrogen 

One of the other common examples of molecules of compounds is nitrogen. The chemical formula of nitrogen is N and having atomic number is 7. Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. Nitrogen is a common element in the universe, estimated as 7th in total abundance in the Milky Way and the solar system.   

3. Ozone 

One of the important nonpolar examples of organic molecules found in nature is Ozone. Ozone is the protective gas that covered the earth to protect humans from the harmful rays of the Sun. the chemical formula of Ozone is O3, and it is made up of three oxygen molecules it is a natural part of the environment. It occurs both in the Earth’s upper atmosphere, or stratosphere, and at ground level in the lower atmosphere or troposphere. This is one of the important examples of small molecules.    

4. Calcium Oxide 

One of the popular examples of diatomic molecules is calcium oxide and its chemical formula is NaO. calcium oxide is also known as lime or more specifically quicklime. It is a white or grayish-white solid produced in large quantities by roasting calcium carbonate so as to drive off carbon dioxide. At standard temperature and pressure, calcium oxide will spontaneously absorb carbon dioxide from the atmosphere. This is one of the common examples of organic molecules.  

5. Carbon Dioxide 

Organic molecules are good examples of molecules and it is carbon dioxide which has the chemical formula of CO2. carbon dioxide is made up of one atom of carbon and two atoms of oxygen. Do you know? CO2 is also called a greenhouse gas. It is used commercially for food and beverage production, metal cooling, fire suppression, and stimulating plant growth in greenhouses. 

6. Structural Proteins 

There are many examples of protein molecules and one of them is a structural protein. It is a category of proteins responsible for functions ranging from cell shape and movement to providing support to major structures like bone, cartilage, hair, and muscles. This group of molecules includes proteins such as collagen, keratin, and actin.  

7. Table Salt 

One of the popular examples of polar molecules is table salt. Table salt is also called rock salt, or sodium chloride and its chemical formula is NaCl. table salt for human consumption is produced in different forms unrefined salt, refined salt, and iodized salt.

Is Co2 A Molecule?

It is a one-carbon compound, a gas molecular entity and a carbon oxide. Carbon Dioxide is a colorless, odorless, incombustible gas resulting from the oxidation of carbon.

What Are 3 Types Of Molecules?

Molecules are of three types: Molecule of an atom, Molecule of an element and Molecule of a compound.

What Are 5 Molecular Substances Examples?

Some examples include: plastic, wood, DNA, proteins, enzymes (a type of protein with a special function).

What Are Simple Molecules?

Simple molecules contain only a few atoms held together by covalent bonds . An example is carbon dioxide (CO 2), the molecules of which contain one atom of carbon bonded with two atoms of oxygen.


By reading this article you have learned all about the types of molecules with examples in detail. Do you know?  There are mainly three types of molecules and they are diatomic molecules, polyatomic molecules, and macromolecules. But, when you differentiate molecules by their chemical bonds then they have mainly two types they are Ionic molecules and covalent molecules. One of the exceptions found in molecules is phosphate ions. Now, you have learned some important examples of molecules.
