Given below are two statements : Statement I : Rutherford's gold foil experiment cannot explain the line spectrum of hydrogen atom. Statement II : Bohr's model of hydrogen atom contradicts Heisenberg's uncertainty principle. In the light of the above statements, choose the most appropriate answer from the options given below :

1. Statement I is false but statement II is true.
2. Statement I is true but statement II is false.
3. Both statement I and statement II are false.
4. Both statement I and statement II are true.

Correct answer: Both statement I and statement II are true.

Solution

Rutherford's gold foil experiment primarily provided insights into the nuclear structure of the atom, but it does not address the quantized energy levels that explain the hydrogen line spectrum. Additionally, Bohr's model, while revolutionary, does not fully align with Heisenberg's uncertainty principle, which highlights the limitations of precisely knowing both position and momentum of particles.
