Question

What does Dalton's atomic model propose?

A) Atoms consist of a small, dense nucleus with electrons orbiting in quantized energy levels.
B) Atoms are like indivisible, solid spheres with no internal structure.
C) Atoms have negatively charged electrons embedded in a positively charged plum pudding.
D) Atoms have a small, dense, positively charged nucleus at the center.

Which model of the atom suggests that electrons orbit the nucleus in specific energy levels and can transition between these levels by absorbing or emitting energy?
A) Thompson's Model
B) Rutherford's Model
C) Dalton's Model
D) Bohr's Model

Answer 1

Dalton's atomic model proposes atoms as indivisible solid spheres without internal structure (Answer B). Bohr's Model is the one that suggests electrons orbit the nucleus in specific energy levels (Answer D).

Step-by-step explanation:

Dalton's atomic model proposes that atoms are like indivisible, solid spheres with no internal structure. So the correct answer to the first question is B) Atoms are like indivisible, solid spheres with no internal structure. As for the model that suggests electrons orbit the nucleus in specific energy levels and transition between these levels by absorbing or emitting energy, this is described by the Bohr Model. Therefore, the answer to the second question is D) Bohr's Model.
