- C.nucleus
- D.neutrons
Show answer and solution
Correct option: C
Solution
Rutherford's gold foil experiment showed that most α-particles passed straight through, but a few were deflected at large angles and some even bounced back. This could only be explained if nearly all the atom's mass and all its positive charge were concentrated in a tiny, dense central region — establishing for the first time the existence of the nucleus. The surrounding space is mostly empty, which is why most particles passed undeflected.
