What problems did Dalton, Thomson, Rutherford and Bohr face with their Atomic Theory?
I cannot find the answer to my questions anywhere:I have to write about Dalton, Thomson, Rutherford and Bohrs atomic theory and how they built onto ea
I cannot find the answer to my questions anywhere:
I have to write about Dalton, Thomson, Rutherford and Bohr's atomic theory and how they built onto each others, however, I cannot seem to find the answers to these questions (especially for Dalton)
the problem that they faced when they started their work (what they were trying to figure out or determine)
How they tested for it
Their solution based on their results of their experiment.

or:Thomson proposed the pudding.model of atom.with a positive sphere and elections embedded in it to make the atom neutral but with rutherford\"$ alpha scattering experiment he found out that the positive sphere is centred and most of atom was empty.his model was the planetary model of atom.With ve nucleus as sun and planets as electrons moving around in circular orbits.But according to Maxwell\"s electromagnetic theory, charged particles when accelerated emit electromagnetic radiations.it will lose its energy and crash into the nucleus.Bohr model couldnt explain1)Dual nature of matter2)heisenburgh's uncertainty principle3 de broglies matter wave4 zeeman effect5 stark effect6 it worked only for hydrogen like speciesDaltonDrawbacks1Atoms wasn't the smallest part of matter - electrons prot etc were discovered2All atoms of a given element may not show same behaviorEg isotopes3 isobars are difft elements with same masses4 compounds with complex ratios are presentEg complex hydrocarbons 5 atoms can be destroyed using nuclear fission and new compounds can be created etcU can confirm it on wikip
