Models of the Atom Timeline
Tyler DeWitt・2 minutes read
Ancient Greek philosophers introduced the concept of atoms as indivisible particles, later expanded upon by Dalton, Thompson, Rutherford, Bohr, and the quantum mechanical model, leading to the modern understanding of atoms and subatomic particles. These scientists' experiments and theories revolutionized the understanding of matter, revealing the complex structure of atoms and the behavior of electrons within them.
Insights
- Democratus and Leucippus introduced the concept of atoms as indivisible particles over 2,500 years ago, envisioning them with different sizes and shapes, though their ideas were initially overshadowed by Aristotle's theory of elements.
- The evolution of atomic theory from Dalton's solid ball model to Thompson's Plum Pudding model to Rutherford's nuclear model and finally to Bohr's planetary model and the quantum mechanical model showcases the gradual understanding of atoms' structure, revealing the nucleus, electrons, and the complex orbital patterns they follow within the atom.
