j. j. thomson

1. choose the best answer.

which statement is true about this model?
the particles of the atom are fire, earth, water, and air.
a positively charged core is surrounded by mostly empty space,
and negatively charged electrons orbit the core.
negative electrons float in a \soup\ of positively charged
material.
the atom is not divided into any smaller or subatomic particles.

Explanation:

• Question 5: The model shown is the plum - pudding model of the atom. J. J. Thomson proposed this model. Aristotle was a philosopher with no direct contribution to this atomic model. John Dalton proposed the solid - sphere model of the atom. Earnest Rutherford proposed the nuclear model of the atom.
• Question 6: In the plum - pudding model (proposed by J. J. Thomson), negative electrons float in a “soup” of positively charged material. The idea of particles being fire, earth, water, and air is an ancient concept (not related to this atomic model). The description of a positively charged core with electrons orbiting is Rutherford's model. The statement that the atom is not divided into sub - atomic particles is Dalton's model.

Answer:

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