Study Notes
Nuclear Model
- The atom features a small, dense nucleus located at the center.
- The nucleus carries a positive charge due to protons.
- Electrons orbit the nucleus, analogous to planets revolving around the sun.
Solid Sphere Model
- Atoms are portrayed as dense and solid entities.
- This model lacks consideration for internal structure or subatomic particles.
