Question

Which of the following observation is not true, according to Rutherford's Atomic model?

• A. Most α particles passed straight through the gold foil
• B. A small fraction of the α particles was deflected by small angles
• C. A very few α particles bounced back, i.e., were deflected by angle 180${}^o$
• D. Positive charge and the mass of the atom was spread uniformly throughout the atom

Answer 1

The correct option is D Positive charge and the mass of the atom was spread uniformly throughout the atom

The positive charge and most of the mass of the atom was densely concentrated in an extremely small region. This very small portion of the atom was called the nucleus by Rutherford.

All the other options are true.
