Question

write the function of lead block in Rutherford alpha particle scattering experiment.​

Answer 1

Answer:

Rutherford's experiment utilized positively charged alpha particles (He with a +2 charge) which were deflected by the dense inner mass (nucleus). The conclusion that could be formed from this result was that atoms had an inner core which contained most of the mass of an atom and was positively charged.

Answer 2

Answer:

Since lead has high density and α−particles cannot penetrate through it, that's why lead block was used to keep the source in α−ray scattering experiment.
