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.

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

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

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.

n an experiment, «-particles are allowed to strike a thin gold foil in a vacuum.Almost all the a-particles pass straight through the gold undeflected. Only a very small number of a-particles are deflected from their original path.This result reveals certain features of the atoms of the gold.State what is shown about atoms by the fact thatsome alpha particles deflected back the way they came
