1
Q
what does the alpha particles passing through the gold foil show
A
most of the atom is empty space
2
Q
what does the alpha particles being deflected show
A
nucleus must be positive
(alpha particles are repelling the nucleus due to them both having a positive charge)
3
Q
what does the alpha particles bouncing straight back show
A
the nucleus is dense and that is where most of the mass of the atom is
as level chemistry
