What evidence do scientists have to prove the existence of the nucleus?

Question

this is for my physics homework. please help me i need desperate help

Answer 1

Hi. Hit it with a high speed particle and the particle stops (sometimes).

Answer 2

i believe its the Rutherford experiments. He shot beta particles at a thin film and detected the beta particles on the other side. Most of the beta particles went through however a very small fraction of it was scattered meaning that there was some thing dense in the middle of the atom. He calculated the atom to be mostly empty space with a dense center dense enough to deflect beta particles

Answer 3

It is generally accepted that Ernest Rutherford proved the existence of the nucleus.

Instead of telling you an entire history of his discovery, here is a detailed web site.

What he discovered is the basis for nuclear physics today.

This should give you enough information for your homework.

Answer 4

Yes, Rutherford experimented with alpha particles from a radioactive sourtce and not beta particles which are electrons.

Answer 5

Check the Geiger-Marsden experiment. That's where our understanding of the atomic nucleus began.

Answer 6

rutherfords alpha scattering experiment.
