Question

In Rutherford's gold foil experiment, most alpha particles passed through the gold foil without deflection and were detected on the screen. What caused the particles to pass through without any deflection?
A. a large area of positively charged particles present in the gold foil.

B. the extremely high speed of the alpha particles passing through the gold foil.

C. a small area of negatively charged particles present in the gold foil.

D. empty space in the atoms present in the gold foil.

Answer 1

An atom consists of a positively charged nucleus in the centre

There are electrons around the nucleus which are negatively charged

Most of space around nucleus is empty.

Alpha particles are positively charged

Now in Rutherford's experiment when alpha particles are passed through gold foil, the alpha particles

a) will get rebound from center (repulsion from central positive nucleus)

b) most of them get deflected as most of the part of atom is empty (no charged particle)
