Geiger -Marsden experiment

What was the importance of the Geiger -Marsden experiment in terms of electrons, protons, neutrons?

The Geiger-Marsden experiment showed the nuclear model of an atom. Because some of positively charged alpha particles deflected more than 90 degrees and some bounced straight back, this suggested that the alpha particle was repelled by the positive charge of a nucleus. Protons and neutrons in the nucleus make up most of the mass of an atom, yet they are in a smaller space relative to the entire atom. Most of the atom is made up of empty space which is why most alpha particles passed straight through in this experiment. The empty space is sparsely populated by the atoms electrons that do not compare in mass to protons and neutrons.

will we have to know all the early scientists who propsed differenttheories for the composition of an atom??

As far as it seems on the syllabus these scientists are not required material for the course

Do we have to study the experiment in detail or do we just have to know the concepts and result of the experiment?

I don't think that we need to know the experiment in detail. Just understand the results/concepts!
