Who discovered nucleus in an atom?
Who discovered nucleus in an atom?
The correct option is B E.Rutherford
Explanation for the correct answer
Option B
From the gold foil experiment, Rutherford discovered that every atom consists of a small, dense, positively charged region known as the nucleus.
Explanation for the incorrect answer
Option A
From the cathode-ray experiment, J.J Thomson discovered that every atom consists of negatively charged subatomic particles known as electrons.
Option C
Chadwick observed that when Beryllium was exposed to alpha particles, different kinds of particles were emitted. These particles had about the same mass as protons and carried no charge. Hence, Chadwick named this particle neutron.
Option D
Bose-Einstein condensation was first predicted theoretically by S.N Bose.
Conclusion: Hence option B is correct.
