When atoms are bombarded with alpha particles, only a few in millon suffer deflection, other pass out undeflected. This is because.

When a gold sheet is bombarded by a beam of alpha - particle , only a few of them get deflected whereas most go straight , undeflected . This is because:

When a gold sheet is bombarded by a beam of alpha - particle , only a few of them get deflected whereas most go straight , undeflected . This is because:

When beryllium is bombarded with alpha-"particles" , extremely penetrating radiations which cannot be deflected by electrical or magnetic field are given out. These are

During Rutherford alpha - ray experiment, it was observed that most of the alpha particles passed through the Gold foil without any deflection, a small fraction deflected by small angles and very few bounced back. b) Give the atom model proposed by him.
