Question

Observe the given two statements about \(\alpha\)-particle experiment and Rutherford assumptions. Statement-I: The ratio of atomic radius to its nuclear radius is \(10^5\). Statement-II: In an atom, the majority of the space is vacant. The correct answer is

• A. Both statements I and II are correct
• B. Statement I is correct, but statement II is not correct
• C. Statement I is not correct, but statement II is correct
• D. Both statements I and II are not correct

Hint:

According to Rutherford's model, \[ \boxed{ \begin{aligned} &\text{Atomic radius}\approx10^{-10}\text{ m}, &\text{Nuclear radius}\approx10^{-15}\text{ m}. \end{aligned} } \] Thus, \[ \boxed{ \frac{\text{Atomic radius}}{\text{Nuclear radius}} =10^5, } \] showing that most of the atom is empty space.

Answer 1

The Correct Option is A
