Explanation:
observation
he observe that when he throw alpha rays on golden foil paper 8000(in ncert book original 21000)times only one time it reflect back
reason
nucleus is present
means protons are present i nucleus which reflect ray of alpha particle
features
he discoved a nucleus which tells us that at the middle of atom it contain a group of protons(nucleus)
drawbacks
This atomic model failed to explain stability of atoms. According to the model, electrons revolve around the positively charged nucleus. It's not possible for a long run as we know atoms are stable while any particle in a circular orbit would undergo acceleration.
