Rutherford's Nuclear Model of Atom
- Rutherford conducted the gold foil experiment and proposed the nuclear model of the atom.
- The key features of Rutherford's model are:
- An atom has a dense, positively charged nucleus at its center.
- Nearly all the mass of the atom resides in the nucleus.
- Electrons revolve around the nucleus in circular paths called orbits.
- The size of the nucleus is very small compared to the size of the atom.
EXPLANATION:
- "There is a neutral centre in an atom called nucleus" — This is incorrect because the nucleus is positively charged due to protons, not neutral.
- "Nearly all the mass of an atom resides in the nucleus" — This is a correct observation from Rutherford's model.
- "The electrons revolve around the nucleus in a circular path" — This is also a correct observation according to Rutherford's model.
- "The size of a nucleus is very small as compared to the size of atom" — This is correct and is consistent with Rutherford's findings.
Therefore, the statement in Option 1 is NOT observed in Rutherford's Nuclear Model because the nucleus is positively charged, not neutral.
