Concept:Rutherford's model describes an atom with a tiny, dense, positively charged nucleus and electrons revolving around it in circular orbits.
Explanation:According to Rutherford's model, electrons revolve around the nucleus in circular paths called orbits.
The nucleus is a small, dense, positively charged centre of the atom.
The size of the nucleus is extremely small compared to the total size of the atom.
The gold foil experiment revealed that most of the atom is empty space.
Statement A is correct because electrons move in circular paths.
Statement B is correct because the nucleus carries a positive charge.
Statement D is correct because the nucleus is very small relative to the atom.
Statement C is incorrect because Rutherford never proposed elliptical paths for electrons.
Elliptical orbits were suggested later by Sommerfeld, not by Rutherford.
Therefore, the incorrect statement about Rutherford's model is option C.
Answer:The incorrect statement is option C: Electrons revolve around the nucleus in elliptical paths.
