The reason why rutherford use alpha particle for the experiment
1- they are heavily and positively charged .
2- they donot have any electron
3- as like charges will repel , the same way , these particle also repel and scattered .
4- they are radioactive
5- they have high ionising power .
REASON TO CHOOSE GOLD FOIL
beacuse he is in search of some metals which can produce scintillations when alpha particle will be bombard and strike into it .
and by gold , he can make the foil so thick that he will be able to stusy the property .
HOPE IT HELPS
ALL THE BEST ..

Alpha particles are +ve charged so he thought they will be attracted by -ve charged electrons in the atom.
Also alpha particles are heavy mass 4u and are fast moving hence have considerable energy to penetrate through gold foil or matter
