0Hello friends,
Atomic stucture is an important chapter in class 11.
It's very intresting topic and easy to learn.
Atoms have many sub-atomic particles, among them basic and important are listed below.
They are

2) Prtons,
3) Neutrons.
The arrangement of these sub-atomic particles in an atom are very intresting to know.
Many scientists put their efforts to explain their views in the form theories.
Dalton gave the idea of existence of atoms in his atomic theory.
After discharge-tube experiments, JJ Thomson came with his pudding model of atom and won Noble prize🏆.
After that
Rutherford α-particle scattering experiment,
Bohr's model for hydrogen atom
And Quantum mechanical model.
