Ernest rutherford was a prominent scientist who contributed significantly to the theory of atomic structure. which of the statements are true? select all that apply.(a) rutherford theorized that atoms contain a positively charged region called the nucleus.(b) rutherford devised the plum pudding model to describe the layout of an atom.(c) rutherford disproved the plum pudding model of the atom.(d) rutherford devised the solar system model to describe the layout of the atom.

(A) Rutherford theorized that atoms contain a positively charged region called the nucleus.

(C) Rutherford disproved the plum pudding model of the atom.

(D) Rutherford devised the solar system model to describe the layout of the atom.

Explanation:

Rutherford conducted an experiment in which he took a thin gold particle film on which he passes alpha- particles. He noticed that:

He concluded that:

Most of the space of the atom is empty and in the center of the atom , there is solid mass which is the cause of the alpha particles to come back. He gave the term nucleus to this solid mass.

This prove that Thomson's plum pudding model is incorrect.

Rutherford Model is also known as Planetary model in which the nucleus is the Sun and the electrons revolve around it in orbits.

Hence, all are true except Option (B).

hi,

the capital city of australia is canberra.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
