What is the difference in the atomic models of Thomson and Rutherford answer?
What is the difference in the atomic models of Thomson and Rutherford answer?
Thomson’s plum pudding model of the atom had negatively-charged electrons embedded within a positively-charged “soup.” Rutherford’s gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus. Based on these results, Rutherford proposed the nuclear model of the atom.
What is the main difference between the cloud model of the atom and the modern model?
Moreover, what is the main difference between the cloud model of the atom and the modern model? Answer: The main difference between the two models was about the location of the electron in an atom.
What is the main difference between the Bohr model of the atom and the Rutherford model?
The Rutherford Model shows an atom with electrons orbiting a fixed, positively charged nucleus in set, predictable paths. The Bohr model shows electrons travel in defined circular orbits around the nucleus.
What are the different atom models?
Atomic models
- John Dalton’s atomic model.
- Plum pudding model.
- Rutherford’s model of the atom.
- Bohr’s model of the atom.
- Electron Cloud Model/Quantum Mechanics Model of Atom.

What did John Dalton say about atoms?
Dalton hypothesized that the law of conservation of mass and the law of definite proportions could be explained using the idea of atoms. He proposed that all matter is made of tiny indivisible particles called atoms, which he imagined as “solid, massy, hard, impenetrable, movable particle(s)”.
How did Dalton know how many atoms were in a molecule?
While all atoms of an element were identical, different elements had atoms of differing size and mass. Dalton’s atomic theory also stated that all compounds were composed of combinations of these atoms in defined ratios. Dalton also postulated that chemical reactions resulted in the rearrangement of the reacting atoms.
What evidence did Dalton have that atoms exist?
Dalton’s Experiments Dalton did many experiments that provided evidence for the existence of atoms. For example: He investigated pressure and other properties of gases, from which he inferred that gases must consist of tiny, individual particles that are in constant, random motion.
Did Dalton say atoms are always in motion?
Atoms of the same element are identical. b. Atoms are always in motion. Dalton hypothesized that atoms are indivisible and that all atoms of an element are identical.
Where are atoms found?
Atoms are made up of protons and neutrons located within the nucleus, with electrons in orbitals surrounding the nucleus.
