Current Question (ID: 7453)

Question:

$\text{In Rutherford's experiment, generally, the thin foil of heavy atoms like gold, platinum, etc. have been used to be bombarded by the α-particles.}$ $\text{If the thin foil of light atoms like aluminum etc. is used in Rutherford's experiment, the difference that would be observed from the above results is:}$

Options:

1. $\text{The same results will be observed.}$
2. $\text{More deflection would be observed.}$
3. $\text{There will not be enough deflection.}$
4. $\text{None of the above.}$

Solution:

$\text{Hint: Lighter elements won't be able to cause enough deflection of α-particles.}$ $\text{Explanation:}$ $\text{A thin foil of lighter atoms will not give the same results as given with the foil of heavier atoms.}$ $\text{Lighter atoms would be able to carry very little positive charge. Hence, they will not cause enough deflection of α-particles (positively charged).}$
