Jolpic Science! Atomic Theory for Kids Part One Today we know that everything is made of atoms. But a few centuries ago, there was a time when the existence of atoms was merely a speculation. However in 1808, John Dalton first discovered the atom, and after his discovery, several scientists began to reveal more facts about it. They found that an atom is not truly indivisible but consists of more subatomic particles like electrons, protons, and neutrons. As science evolved, scientists came to know that a moving particle could also behave like a wave, and a new branch of physics called quantum mechanics thus emerged. The entire journey, from the atomic discovery to modern day physics, is quite interesting. In this book series, we are going to discuss almost everything related to atoms and molecules, and how scientists gradually revealed several strange facts through scientific experiments. In this first book of "Atomic Physics for Kids" series, we have discussed how the atom was first discovered and how Dmitri Mendeleev pointed out that the elements periodically show similar chemical properties with their increasing atomic weights.
