Key Stage 4
Meaning
The Nuclear Model is a model of the atom which suggests there is a positively charged nucleus in the centre of an atom with electrons orbiting around the nucleus.
About the Nuclear Model
- The Nuclear Model was first proposed by Ernest Rutherford after he successfully disproved the Plum Pudding Model of the atom using his alpha scattering experiment.
- In the Nuclear Model most of the atom is empty space. The majority of the mass of the atom is concentrated in a small central nucleus. This central nucleus has a strong positive charge while negatively charged electrons orbit the nucleus.
