Concept Map for Atomic Models
Introduction
Atomic models are representations of the structure of atoms. These models have evolved over time as scientists have discovered more about the nature of atoms.
Dalton's Atomic Model
- Dalton's atomic model was proposed in 1803.
- It suggested that atoms were indivisible and indestructible.
- It also suggested that all atoms of a given element were identical.
Thomson's Atomic Model
- Thomson's atomic model was proposed in 1897.
- It suggested that atoms were made up of positively charged material with negatively charged electrons embedded in it.
- This model is often referred to as the "plum pudding" model.
Rutherford's Atomic Model
- Rutherford's atomic model was proposed in 1911.
- It suggested that atoms had a small, positively charged nucleus at the center with negatively charged electrons orbiting around it.
- This model is often referred to as the "planetary" model.
Bohr's Atomic Model
- Bohr's atomic model was proposed in 1913.
- It suggested that electrons orbit the nucleus in specific energy levels or "shells".
- This model helped to explain the emission and absorption spectra of elements.
Quantum Mechanical Model
- The quantum mechanical model was developed in the 1920s and 1930s.
- It suggests that electrons exist in a probability cloud around the nucleus rather than in specific orbits.
- This model is often represented by the electron cloud model.
Conclusion
Atomic models have evolved over time as scientists have discovered more about the structure of atoms. Each model has contributed to our understanding of the nature of matter.
