To determine:
The conclusions that can be drawn from the experiment (Rutherford) about the structure of an atom.
Introduction:
The experiment done by Ernest Rutherford in which the particle beam passes the piece of gold foil that is made up of only few atoms, this is because the positive charged particles passes the spaces between the atoms in the foil.

Explanation of Solution
The group of atoms combines to form the elements. The elements consist of as many atoms as possible which are packed and have a space between them. The atoms are the smallest unit that is made up of protons, neutrons and electrons. These many atoms combine to form molecules and then the molecules combine to form elements. A piece of foil is also made up of atoms which are packed and have some space between them.
In this experiment, a beam of positively charged particles is passed through the gold foil in which only few particles are deflected and maximum particles passes through the foil. There is no change in the path of the passing beam particles is seen.
The two conclusions that are observed in this experiment:
- 1. The atoms present in the foil must have enough space that the positively charged particles can easily pass through the foil. The particles that pass between the spaces of atoms does not get influenced or repelled by the positive charges present in the atoms of the foil.
- 2. Another conclusion is that the size of positively charged protons present in the atoms is so small and compact that they are not able to make contact with the coming positively charged particles.
The beam particles pass through the spaces present between the atoms. As they are positively charged, they are not hindered by the protons of atoms.

How does your team wish to delineate the domain or scale in which these objects or events operate? How does that limited domain facilitate a more feasible research project? What is your understanding of their relationships to other objects and events? Are you excluding other things from consideration which may influence the phenomena you seek to understand? Examples of such exclusions might include certain air-born pollutants; a general class of water bodies near Ottawa, or measurements recorded at other months of the year; interview participants from other organizations that are involved in the development of your central topic or issue.

A researcher created a group of osteoblasts with an Esp mutation that prevented the production of a functional Esp product (mutant). The researcher then exposed the mutant strain and a normal strain that expresses Esp to glucose and compared the levels of insulin in the blood near the osteoblasts (Figure 2). Which of the following claims is most consistent with the data shown in Figure 2 ? A Esp expression is necessary to prevent the overproduction of insulin.
