Question

Watch the animation depicting Rutherford’s experiment and choose which of the following conclusions are correct.a. The atom contains a positively charged nucleus. b. Positive charge is condensed in one location within the atom. c. The majority of the space inside the atom is empty space. d. A positive charge is spread equally over the atom. e. The mass of an atom is concentrated at the nucleus. f. The atom is a very compact entity without any em

Answer 1

Answer:

a, b, c, d

Explanation:

Rutherford’ atomic model is based on the gold foil experiment. In this experiment, beam of alpha rays was bombarded on thin gold foil. He observed that:

Most of the alpha particles passed through thin foil without any deflection.

Few alpha particles deflected by an angle of 90o.

Based on observation, Rutherford concluded that majority of the space inside the atom is empty.

He explained defection of few alpha particles by assuming that most of the mass is concentrated at the nucleus and positively charged.  

Therefore, among given, the correct statements are:

The atom contains a positively charged nucleus.

Positive charge is condensed in one location within the atom.

The majority of the space inside the atom is empty space

The mass of an atom is concentrated at the nucleus

Therefore, the correct options are:

a, b, c, d
