Question

briefly explain the structure of an atom

Answer 1

atom is made up of three subatomic particles are electron proton and neutron. Electrons have negative charge protons has positive charge where is neutron has no charge it is neutral.
discovery of electron the existence of electron in an atom was shown by JJ Thomson in 1897. cathode rays consist of small negative charged particles called electrons.
discovery of proton the existence of proton in the Atom was shown by E.Goldstein. the anode rays obtained from hydrogen gas consists of proton Proton is A positively charged particle found in the atom of all elements.
discovery of neutron this problem was solved by the discovery of subatomic particles by James Chadwick in 1932. the sub atomic particle not present in a hydrogen atom is neutron.
the discovery of electron and proton suggested that Atom was divisible and they do not have an inner structure this at home son was the first scientist to propose a model for the structure of atom.
Thomson's model of the atom -
when did Je Thompson proposed which model of the atom in 1903 they only electron and proton were known to be present in the atom.
