Fill in the blanks in the following statements (a) Rutherford’s α-particle scattering experiment led to the discovery of the ———

On the basis of Rutherford’s model of an atom, protons (positively-charged particles) are present in the nucleus of an atom.

If the α-scattering experiment is carried out using a foil of a metal rather than gold, there would be no change in the observation. In the α-scattering experiment, a gold...

(c) Nucleus in the atom

(a) (i) and (iii)

(b) (ii) and (iv) 

Hint— gold has high malleability

Rutherford concluded from the α-particle scattering experiment that–  (i) Most of the space inside the atom is empty because most of the α-particles passed through the gold foil without getting deflected.  (ii)...

In the alpha-particle scattering experiment, if a thin sheet of solid hydrogen is used in place of a gold foil, then the scattering angle would not be large enough. This...
