Difference Between Molecule And Compound

Is it getting very hard for you to make difference between molecule and compound? Don’t worry about it, today I will tell you about how simple it is. We will discuss what are these molecules and compounds? You will come to know what is the definition, examples of compound vs molecule, etc. Read till last so that you will not miss any of the important points. Let us understand the difference between molecule and compound without making any delay.

What’s Difference Between Molecule And Compound?

The difference between molecule and compound is very simple to understand. However, let us know about what is a molecule and what is a compound before seeing the differences. This will put more value to our understanding and helps us to easily differentiate them.

A molecule is made up of atoms and a compound is made up of molecules. Both things may look related to each other but it is very important to study their difference individually.

So let us know about them quickly by seeing what is the major difference between molecule and compound. I have described the definition of them further.

What Is A Molecule?

A molecule is a substance that is made up of at least two or more atoms. These atoms of an element are connected with the help of chemical bonds. A molecule is a small unit of a compound. It can promote the characteristic of a compound.

What Is A Compound?

A compound is a molecular substance that is made up of two or more and same or different atoms. These atoms are linked with each other by chemical bonds within a particular ratio or structure. There are three different bonds such as covalent, ionic, and metallic bonds.

A compound is constructed of different molecules in general. It is said that every compound can be a molecule however every molecule can not be a compound. 

Now let us learn about the difference between compound and molecule one by one for better understanding.

  • Definition

The definition will help us to know the meaning of the compound and molecule.

Molecule

The molecule can be defined as a chemical structure in which two or more only same atoms are connected chemically.

Compound

The compound can be defined as when two or more different or same elements are combined by chemical bonds.

  • Examples

It is easy to study the difference between molecule and compound with examples. Below are some of the common examples of both.

Molecule

Oxygen, Ozone, Dinitrogen, Hydrogen are examples of the molecule.

Compound

Different examples of compounds are Calcium carbonate, Nitric Acid, Water, Salt, etc.

  • Properties

Properties also make a difference between molecule and compound in chemistry. So let us see what is their properties.

Molecule

Molecules can be in two forms such as heteronuclear molecules and homonuclear molecules. The heteronuclear molecules 

Compound

  • Stability

Stability is understood based on a difference between molecule and compound and element in both. Further, I have described it generally.

Molecule

The stability of a molecule depends upon the atoms in it. Sometimes they can be stable while sometimes they can be unstable.

Compound

The compounds are more stable than the molecules because of their structural arrangement. This helps compounds to possess physical structure.

  • Types of bonds

Yes, you heard it right there are different bonds in the molecule as well as compound.

Molecule

Molecules have two bonds mainly ionic or covalent. These bonds help to links atoms or groups of atoms with each other.

Compound

In the compound, bonds can be ionic, metallic, and covalent. This tells us the difference between compound and element or molecule. It is considered as all the compounds are molecules, but all molecules are not compound.

  • Visibility

The visibility states the difference between atom, molecule and compound to understand their chemistry.

Molecule

Molecules are made from the bonding of two or more atoms. Hence, they are not visible to our naked eyes.

Compound

Compounds are made from molecules and elements which helps them to have a physical structure. Hence compounds are visible and can be seen without naked eyes.

  • Structure

Below is the structure and differences between molecule vs compound. Please read it carefully.

Molecule

Here to know the difference between molecule and atom the oxygen is the best example. In oxygen, you will find two oxygen atoms bonded with each other and the structure is O2.

Compound

In the compound, the difference between atom and element should be known. So the common salt had one sodium atom and one Chloride atom. Which can be denoted by Na and Cl respectively. When these two elements are combined they form Sodium Chloride that is NaCl.

  • Formula

The formula is one important factor that helps us to understand the difference between compound and mixture.

Molecule

Nitrogen is a molecule, as there are two atoms of nitrogen bonded the formula is N2.

Compound

Sugar is a compound, as it contains carbon, hydrogen, and oxygen atoms. The formula of sugar is C12H22O11

One more example of a compound is water, which contains hydrogen and oxygen and the formula is H2O.

FAQ

What Is The Main Difference Between Molecule And Compound?

The main difference between molecule and compound is the atoms. These atoms of an element are connected with the help of chemical bonds. In a molecule, two or more same atoms are connected with the chemical bonds. However, in a compound, two or more, same or different atoms and molecules are connected. Since a molecule is a small unit of a compound. It can promote the characteristic of a compound.

Is Water A Molecule Or Compound?

Water is a compound because it contains two different atoms such as two hydrogen atoms and one oxygen atom.

What Is A Molecule But Not A Compound?

Hydrogen gas (H2) is an example of a molecule but not a compound. Other such examples are oxygen gas (O2), nitrogen gas (N2), etc.

What Is The Difference Between Atom Molecule And Compound?

The difference between atom, molecule, and compound is that the same atoms when connected with ionic or covalent bonds they form molecules. And when molecule as well as same or different atoms connected with chemical bonds for compounds.

Conclusion

In this topic, we learned the difference between molecule and compound in chemistry. How they are related but have many differential points. I told their definition, examples, structure, formula, etc of molecules and compounds. You will now not get any issues while distinguishing between compounds and molecules in the future. I explained the factors related to the molecules and compounds which will be helpful for you. We understood how atoms and elements create the difference between molecule and compound.
