Question

Why does the alpha particle not make physical contact with nucleus

Answer 1

Explanation:

Explanation: Sometimes they do and sometimes they don't; it all depends on their energy. ... If the alpha particle energy is high enough, then it can either pick up a neutron of proton from, or deposit one of its neutrons or protons in an atom of the target. It can also just bounce off
