Question

In Rutherford's scattering experiment, which of the following does not happen?

• A. Most of the $\alpha$-rays pass through without deflection.
• B. A few $\alpha$-particles pass through the nucleus.
• C. A few $\alpha$-particles are deflected back.
• D. $\alpha$-Particles going near the nucleus are slightly deflected.

Answer 1

The correct option is B

A few $\alpha$-particles pass through the nucleus.

What is $\alpha$-particle?

$\alpha$-particle $\to$ ${}_2^{4}He$

Now, we know that nucleus was present at the centre and α-particles cannot pass through nucleus because most of the weight of atom is in nucleus and it was very heavy in the case of Gold.
