Question

From Rutherford's alpha particle scattering experiment give the experimental evidence for deriving the conclusion that

Answer 1

Most of the space inside the atom is empty : this was concluded because most of the alpha particles fired at the gold foil pass through without any deflection.

The nucleus of an atom is positively charged : this was concluded because some of the alpha particles (positively charged) were deflected of bounced back along the initial path. This repelling force was only possible when the nucleus was positively charged.
