Study Notes
Neutron Discovery
- The discovery of neutron was made by James Chadwick in 1932.
- The neutron was discovered in the year 1932.
Neutron Characteristics
- Neutron is present in the nucleus of all atoms.
- Neutron is present in the nucleus of all atoms.
Thomson's Atomic Model
- Also known as the "plum pudding" model, proposed by J.J. Thomson in 1904
- First atomic model to describe the structure of atoms
Composition
- Positive sphere: Atom composed of a sphere of positive charge
- Negatively charged electrons: Embedded within the positive sphere
- Uniform distribution: Electrons are uniformly distributed throughout the positive sphere
Characteristics
- No nucleus: There is no central nucleus in Thomson's model
Limitations
- Failed to explain: Zeeman effect and the Stark effect
- Lacked experimental evidence: Model not supported by experimental evidence
- Later disproven: Model disproven by Ernest Rutherford's gold foil experiment in 1911, leading to the development of the Rutherford model
