Question

Rutherford's Q - particle scattering experiment showed that
O electrons have negative charge
(ii) the mass and positive charge of an atom is concentrated in the nucleus
(iii) neutron exist in the nucleus
(iv) most of the space in the atom is empty *
Select the correct 2 :

Answer 1

Answer:

2th and 4th

Explanation:

In his gold foil experiment Rutherford observed that most of the alpha particles which are positively charged particles went straight through the foil without any deflection so he concluded that most of the space in the atom is relatively empty.

Few alpha particles deflected by large angles with a 180

0

made him conclude that mass and positive charge is concentrated at the centre of the atom.

Hence option (B) is correct.
