Question
On the basis of the atomic model Rutherford concluded that:A atoms consist of predominantly empty spaces B atoms consist of central nucleus containing positively charged particles C whole of the atomic mass is concentrated in the nucleus D All of these
Solution
D. All of these
Rutherford's atomic model led to several conclusions:
A. Atoms consist of predominantly empty spaces: Rutherford's gold foil experiment showed that most of the alpha particles passed straight through the foil, suggesting that atoms are mostly empty space.
B. Atoms consist of a central nucleus containing positively charged particles: Some alpha particles were deflected at large angles or even bounced back, indicating a small, dense, positively charged nucleus.
C. The whole of the atomic mass is concentrated in the nucleus: Since the nucleus contains the protons and neutrons, which have much more mass than the electrons in the electron cloud, almost all of the atomic mass is concentrated in the nucleus.

Use the evidence described to explainwhy Rutherford concluded that:a an atom contains a lot of spaceb there is a central area of positive charge.
Ernest Rutherford fired α-radiation at an incredibly thin sheet of gold foil. Not all particles went through the gold foil. Some were deflected, and some bounced right back.Recall what this meant for the structure of the atom. Atoms are mostly empty spaces with a tiny charged nucleus orbited by electrons.1Atoms are solid with no empty space.2Atoms are made up of a positive matrix with negative electrons mixed in.3Atoms have a very large charged nucleus.
Recall which of the following statements is a part of Rutherford's model of the atom. Atoms cannot be divided into smaller particles.1Atoms are solid spheres.2Electrons orbit the nucleus.3
