In 1911, the physicist Ernest Rutherford discovered that atoms have a tiny, dense nucleus by shooting positively charged particles at a very thin gold foil. A key physical property which led Rutherford to use gold was

Q. Statement 1: A large number of alpha particles were deflected in the Rutherford experiment.
Statement 2: Alpha particles that came close to the nucleus were deflected.

I

. During Rutherford's gold foil experiment, a beam of alpha particles was directed at a thin sheet of gold foil. This helped to prove the existence of a nucleus in the atom.

I I

. Most of the positively charged alpha particles were able to pass undeflected through the gold foil.

Which of the following conclusions can be drawn from the Rutherford alpha scattering model?

I. The atom is mostly empty space.
II. Electrons orbit the nucleus of the atom.
III. The atom has a dense, positively charged nucleus.

Q. Assertion : According to Rutherford, Very few particles were deflected from their path, indicating that the positive charge of the atom occupies very little space Reason: Mass of the atom is almost due to its nucleus.
