Write 2 differences between J.J. Thomson's
model of an atom and Rutherford's model of
an atom.
Answers
Answer:
JJ Thomsons model:J.J. Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons.
Thomson's plum pudding model of the atom had negatively-charged electrons embedded within a positively-charged "soup."
rutherford model :The positively charged particles and most of the mass of an atom was concentrated in an extremely small volume. He called this region of the atom as a nucleus.
Rutherford model proposed that the negatively charged electrons surround the nucleus of an atom. He also claimed that the electrons surrounding the nucleus revolve around it with very high speed in circular paths. He named these circular paths as orbits.
Answer:
- J.J Thomson's model of an atom ped to the discovery of electrons whereas Rutherford's model of atom led to the discovery of nucleus.
- Thomson's model depicted that an atom is a positively charged spere in which electrons are scattered on it whereas Rutherford 's model depicted that an atom has positively charged centre where the entire mass of an atom lies
