History of atomic theory

Somewhere around 440 BCE Democritus proposed that everything in the world was made up of tiny particles surrounded by empty space. And he even speculated that they vary in size and shape depending on the…

Introduction to Nucleus

nuclear physics

All nucleus are made up off protons and neutrons. A proton has the charge value equal to electron but the mass of electron is negligible as compared to protons and neutrons. In nuclear physics, each…
