JEE Mains · Chemistry · STD 11 - 2. structure of atom
Given below are two statements: Statement \(I :\) Rutherford's gold foil experiment cannot explain the line spectrum of hydrogen atom. Statement \(II :\) Bohr'smodel 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 :
- A Statement \(\mathrm{I}\) is false but statement \(II\) is true.
- B Both statement \(I\) and statement \(II\) are false.
- C Statement \(\mathrm{I}\) is true but statement \(II\) is false.
- D Both statement \(\mathrm{I}\) and statement \(II\) are true.
Answer & Solution
Correct Answer
(D) Both statement \(\mathrm{I}\) and statement \(II\) are true.
Step-by-step Solution
Detailed explanation
Rutherford's gold foil experiment only proved that electrons are held towards nucleus by electrostatic forces of attraction and move in circular orbits with very high speeds. Bohr's model gave exact formula for simultaneous calculation of speed \(\&\) distance of electron from…
