Question

1. choose the best answer. which statement is true about this model and the postulates its based on? a positively charged core is surrounded by mostly empty space, and negatively charged electrons orbit the core. the atom is not divided into any smaller or subatomic particles. negative electrons float in a soup of positively charged material. the particles of the atom are fire, earth, water, and air. 3. choose the best answer. who proposed this model? earnest rutherford aristotle john dalton j. j. thomson

Explanation:

• For the first question:
• The model described in option A is Rutherford's model.
• Option B is Dalton's model (atom as indivisible).
• Option C is Thomson's plum - pudding model (electrons in a positive 'soup').
• Option D is an ancient, incorrect view.
• For the second question:
• Earnest Rutherford proposed the nuclear model (positive core with electrons orbiting).
• Aristotle had non - scientific views on matter.
• John Dalton proposed the atomic theory with indivisible atoms.
• J.J. Thomson proposed the plum - pudding model.

Answer:

1. A. A positively charged core is surrounded by mostly empty space, and negatively charged electrons orbit the core.
2. Earnest Rutherford.
