which scientist developed the first model of the atom that proposed the structure of the inside of an atom?\ndalton\nbohr\nrutherford\nthomson
Answer
Brief Explanations:
- Dalton's model was a solid - sphere model and did not propose the internal structure of the atom.
- Bohr's model was about the quantization of electron energy levels in an atom, but it was not the first to propose internal structure.
- Rutherford's model (nuclear model) was after Thomson's.
- Thomson discovered the electron and proposed the "plum - pudding" model which was the first to propose an internal structure of the atom (with electrons embedded in a positively - charged "soup").
Answer:
Thomson
