Atoms are the small particles of matter. These particles have sub-atomic particles.
What are the sub-atomic particles of atom?? Who discover the atom?
Democritus was the first one to discover atoms.
Protons,electrons and neutron are the sub-atomic particles of an atom.
Who are the other scientists who discovered about atoms?
John Dalton created the first atomic theory.His theory was that atoms were tiny indivisible solid balls .Atoms are tiny solid balls that are indivisible.John Dalton also found the atomic mass along with other scientists
In the year 1897, JJ Thomson found out that there are negatively charged particles inside the Atom. He called these corpuscles but scientists then changed the name into what we call today as "electrons".JJ Thomson was the first scientist to discover evidences of Isotopes. My atomic model is the "Plum Pudding" model.
hmmm. who are the next scientist after JJ Thomson?
In the year 1910, Ernest Rutherford discovered the Nucleus and he also discovered the Protons inside the Nucleus through the Gold Foil experiment. He discovered that most of the particles went through the Gold in the experiment. The atom had a dense center which I call the Nucleus.
Then who's next???
Neil's Bohr improved Rutherford's model by proposing that electrons move around the nucleus in specific layer or shells. Then James Chadwick discovered neutrons while working with Rutherford. The model (1932) word done since 1920 has changed the model. The new atomic model has electrons moving around the nucleus in a cloud.
Ohhh! Thank you so much sir. I have lot of knowledge about atoms.
