Question

look at the model. then, choose the best answers. 3. choose the best answer. which statement is true about this model? negative electrons float in a \soup\ of positively charged material. the particles of the atom are fire, earth, water, and air. the atom is not divided into any smaller or subatomic particles. a positively charged core is surrounded by mostly empty space, and negatively charged electrons orbit the core. 4. choose the best answer. who proposed this model? john dalton

Explanation:

The model shown is the plum - pudding model of the atom. In this model, negative electrons are embedded in a positively charged "soup". Thomson proposed the plum - pudding model. John Dalton's model considered atoms as indivisible spheres. The statement about fire, earth, water and air is from ancient philosophy and not related to this atomic model. The idea of a positively charged core with electrons orbiting is the Rutherford model.

Answer:

1. Negative electrons float in a "soup" of positively charged material.
2. J. J. Thomson
