What is Chemistry?| Definition and Branches

What is Chemistry?

Chemistry represents the section of the natural science that represents the physical properties, composition, structure and their cause and ways to synthesise into other forms of substance  and their interrelationship with energy.Other branches like Physics,Biology etc are also concerned with the matter but Chemistry is the in-depth study of matter which also relates to the changes or reactions that matter undergoes ;how and why they form into different substances and the energy required to bring about the changes or reactions .So it simply implies that chemistry is a part of  everything in our daily lives and also acknowledging the conceptions of chemistry might educate us with important explanations of how and why certain matters behave the way they do .

Since chemistry is involved in explicating the behavioral, structural, compositional and physical properties of matter, it’s quite certain that matter is the basis of chemistry; so it’s essential to know what the fundament of matter is.

Matter: Are any substances that have masses. As we know ‘Atom’, the basic building block of everything that in the universe; so it’s pretty understandable that matter is composed of atoms which ultimately forms the basis of scientific study, that is Chemistry. So from our bodies to everything existing in or beyond the universe is made up of atoms that suggests chemistry is a part of everything that exists in and beyond the universe.

Some Branches of Chemistry:

Although the number of branches in Chemistry is quite disputable as other sub-branches could originate from the main branches, such as Macromolecular Chemistry, Theoretical Chemistry, Nuclear Chemistry, Metallurgy and so on.Yet it wouldn’t be unfair to describe the five branches of Chemistry that’s considered fundamental by many.

Analytical Chemistry: It’s the analysis of the physical and chemical properties of matter by methods and examinations of quantification and qualification of it.

Physical Chemistry: It’s that part of the chemistry which is concerned with the implementation of concepts and laws of physics in chemical systems e.g. the interconnection of matter and energy.

Some of the sub-branches of physical chemistry are:

Thermodynamics: That studies the interrelationship of energy and chemical changes.

Electrochemistry: The study concerned with interconnection of atoms, molecules, ions and their electric charges.

Quantum mechanics: That studies the quantum mechanics and their interrelationship with chemical phenomenon.


Organic Chemistry: It’s the study concerned with the properties of compounds comprised of carbons (an element).A few sub-branches of organic chemistry:

Organometallic Chemistry: Chemical study of bonds between a carbon and metal.

Polymer Chemistry: Physical study of composition of polymer molecules and how they are formed.

Medicinal Chemistry: The study of devising, evolving and synthesizing of pharmaceutical drugs.

Inorganic Chemistry: Being the exact opposite of organic chemistry, it studies the properties of non-carbon compounds.Some of the sub-branches are:

Geochemistry: Chemical study of Earth’s composition, rocks, minerals and atmosphere.

Nuclear Chemistry: Study of radioactive matters.

Synthetic Inorganic Chemistry: Studies the synthesis of chemicals.

Biochemistry: It studies the chemical processes occurring in the biological systems.Sub-branches of biochemistry includes:

Enzymology: Study concerned with enzymes.

Endocrinology: Branch that studies the hormones.

Molecular Biochemistry: Study that involves biomolecules and their functions.

Advancements in the field of Chemistry  has led to significant progression in our world.Chemists study the natural world to bring about ameliorations to our lives on a molecular level by modifying it.It provides us with new directions to advance from the existing criteria contributing significantly in the modern Sciences.
