Chemists in a social and historical context: The atom detectives
Specification
- England
- A/AS level
- GCSE
- AQA Chemistry
- 4.1 Atomic structure and the periodic table
- 4.1.1 A simple model of the atom, symbols, relative atomic mass, electronic charge and isotopes
- 4.1.1.3 The development of the model atom
- New experimental evidence may lead to a scientific model being changed or replaced.
- Before the discovery of the electron, atoms were thought to be tiny spheres that could not be divided.
- The discovery of the electron led to the plum pudding model of the atom. The plum pudding model suggested that the atom is a ball of positive charge with negative electrons embedded in it.
- The results from the alpha particle scattering experiment led to the conclusion that the mass of an atom was concentrated at the centre (nucleus) and that the nucleus was charged. This nuclear model replaced the plum pudding model.
- Niels Bohr adapted the nuclear model by suggesting that electrons orbit the nucleus at specific distances. The theoretical calculations of Bohr agreed with experimental observations.
