What did Joseph John Thomson conclude about the atom?
J.J. Thomson discovered the electron and proposed the plum-pudding model for the atom.
How relevant is John Dalton's atomic theory to today's understanding of the atom?
He proposed that each element consists of atoms of a single, unique type, and that these atoms can join together to form chemical compounds.[17][18] Dalton is considered the originator of modern atomic theory.[19]Dalton's atomic hypothesis did not specify the size of atoms. Common sense indicated they must be very small, but nobody knew how small. Therefore it was a major landmark when in 1865Johann Josef Loschmidt measured the size of the molecules that make up air.My opinion is there is no relevant between John Dalton's atomic theory today's understanding the atom.READ:Note: John Joseph Thomson - He is credited for the discovery of the electron and of isotopes, and the invention of the mass spectrometerErnest Rutherford - he postulated that atoms have their positive charge concentrated in a very small nucleus,[3] and thereby pioneered theRutherford model, or planetary, model of the atom.Niels Bohr -The Bohr model of the atom, the theory that electrons travel in discrete orbits around the atom's nucleus.The shell model of the atom, where the chemical properties of an element are determined by the electrons in the outermost orbit. The liquid drop model of the atomic nucleus.Identified the isotope of uranium that was responsible for slow-neutron fission James Chadwick - James Chadwick was the first man to discover the neutron-the neutrally charged particle of the nucleus (which also contains protons, positively charged particles). Electrons whizz around the nucleus (which is the heaviest part by far of the atom) on "orbits". Note: There are comments associated with this question. See the Discuss:What_was_james_chadwick_contribution_to_the_atomto add to the conversation.
The bohr model is an innaccurate model of the atom because there is no way to measure the exact of an electron in an atom?
It is an inaccurate model, because there is no way to measure the exact mass, path, and charge of an atom
Wave mechanical model of the atom?
mass number and atomic number of an atom
The bohr model of the atom resulted from the developement of?
Quantum Theory
Who formed the atomic theory model of the atom and was an English schoolteacher?
John Dalton
Who came up with the proton model of the atom?
John Dalton
Who came up with the 4-part atomic theory in 1805?
The first person to develop the first model of the atom in 1803 was John Dalton.
What was the name of Dalton model?
Dalton's atomic model is one of the fundamentals of physics and chemistry. John Dalton named this model after himself.
Which scientist first made a model of the atom with subatomic particles?
John Dalton
Which event would be impossible to explain by using John Daltons model of the atom?
A Dalton's model of atom doesn't exist. Dalton principles are not in agreement with the discovery of isotopes and nonstoichiometric compounds.
What is the billiard ball model?
The billiard ball atom model was proposed by John Dalton.
What is is billiard ball model?
The Billiard Ball Model is John Dalton's idea of what an atom looks like.
Who is model of the atom has no subatomic particles?
Both Democritus' and John Dalton's atomic models had no subatomic particles.
Where did john Dalton find the atom?
john dalton didnt find the atom democrites did... john dalton was reading and found the word atomos in a journal and decided he would change the name to atom meaning undivisible.
How did thomsons atomic model differ from daltons model?
If i remember correctly, Dalton's focuses more on the nucleus while Thompson's focuses more on electrons. But I'm not sure. well in 1803 John Dalton makes a strong case that atoms are small, solid balls and Joeseph John Thompson discovers electrons, and developed plum pudding model of an atom..... Dalton says that nothings smaller than the atom, but Thompson says that electrons are.
Who discovered the nuclear model?
Ernest Rutherford created the nuclear model of an atom!
