Guida verificata passo dopo passo1
Recall the historical development of atomic models to understand the context of J.J. Thomson's contribution.
Identify that J.J. Thomson proposed a model where electrons are embedded within a positively charged 'soup' or 'cloud', resembling a dessert with embedded fruits.
Recognize that this model is commonly called the 'Plum pudding model' because it likens electrons to plums within a pudding of positive charge.
Compare this with other atomic models: the 'Planetary model' is associated with Rutherford, the 'Quantum mechanical model' with Schrödinger and others, and the 'Solid sphere model' with Dalton.
Conclude that the name commonly used to refer to J.J. Thomson's atomic model is the 'Plum pudding model'.
