Chemistry as a disciple is truly a fascinating realm of magical possibilities. As we know, atoms form the basis of everything that we know about and thus, the atomic theory is practically the theory of almost the basis of everything around us. In this blog, we are going to try to understand the fundamental building blocks of chemistry through Atomic Theory.  

Students, teachers, home tutors and nerdy enthusiasts alike, are you ready to embark on this thrilling and enlightening journey?

Dalton’s Billiard Ball Model:

The fundamentals of chemistry and the infinite worlds of possibilities in understanding the universe around us, starts with none other than John Dalton. In the early 19th century, John Dalton proposed his idea about tiny indestructible particles that form the basis of matter which looked like the balls in a billiard table. According to his theory, every element had similar atoms and chemical reactions occurred when these identical atoms were forced to change their composition.

Thomson’s Plum Pudding Model:

Fast forward to J.J. Thomson, we have the first official discovery of the electron. His theory revolutionised the world of chemistry since the idea of subatomic particles were put forward. He put forward the ‘plum pudding’ format where the atom is compared to the pudding with negatively charged particles or electrons embedded in it.

Rutherford’s Gold Foil Experiment:

Ernest Rutherford made a stir in the atomic world with his Gold Foil Experiment when he found out that most of an atoms’s mass is concentrated in a small, positively charged sphere, essentially creating the nuclear model of an atom. 

Bohr’s Planetary Model:

Following Ruherfor and his nuclear model came Bohr, who further developed the model and proposed the planetary format theory where negatively charged particles or electrons orbited a positively charged nucleus like the planets in our solar system orbits the Sun.

All of these groundbreaking researches, theories and findings has given us the advanced concepts that we have today, such as the theory of Quantum Mechanics. Isn’t it fascinating how disciplines develop over time and how much we owe our everyday life, luxuries and knowledge to hundreds and thousands of people who have worked hard before us.
