Question

Which of the following is not correct observation conclusion from Rutherford's scattering
experiment?
(a) Nucleus is small but heavy
(b) Nucleus always carries positive charge
(c) Atom is nearly 10^5 times greater than the size of the nucleus
(d) The number of particles hitting the nucleus is very large
​

Answer 1

Answer:

Very few of bombarded α-particles on gold foil were deflected by sharp angles and therefore, it was concluded that the positive charge is concentrated in a very small volume of the atom called nucleus. Since few were deflected, the size of the nucleus is very small as compared with atom size.

Most of the particles passed through the foil undeflected and was concluded that most of the space in an atom is empty.
