What is the gold foil experiment? Name the scientist who performed this experiment. Write the conclusion and shortcomings of Rutherford 's model of atom.
Answers
this experimrnt was done by rutherfurd to find the structure of atom
he passed alpha particles through the gold plate
he observed some passed straight without any deflection, som got a little deflected, and some completely reflected
he concluded that atom was made of a sphere with a heavy centre called nucleus and negative particles i.e. e- revolved around....
short mai hai.. but it might help...
Answer:
Rutherford's Gold Foil Experiment:
Rutherford took a very thin gold foil with 100 nm thickness. He bombarded the gold foil with alpha rays. It is important to note that alpha particles are positively charged.
Observations made by Rutherford:
⋅ Most of the alpha rays passed through the gold foil without any deviation in path.
⋅ Some of the alpha rays showed slight deviation.
⋅ A very few alpha radiations bounced back to their source.
Rutherford's Conclusions:
⋅ A major portion of atom is hollow and bears no charge. Hence, most of the alpha rays passed through without deviation.
⋅ Some of the alpha-rays showed slight deviations means that there is a positively charged portion in atom. The positive charge in atom offered repulsive force on alpha particles.
⋅ Very few alpha rays bounced back means that the positively charged portion's size is very small compared to the overall size of atom.
