f)Draw a table in your notebook that indicates the substance,whether it is soluble in water and whether it conducts electricity or not. The table can be like the following:

2Make a comparative table with the experimental results of the materials evaluated. Include the molecular structure, types of elements or compounds, and possible uses, among others.

BUILDING AND/OR PROVING The Possible Paths

Now, it is important to compare the hypothesis you chose with the information obtained. As a community, do the following:

1. Review the results of the experimentation and investigation and the annotations made from bibliographic sources.

2. Do a table to compare the elements and compounds that were similar, and the investigated and experimental results obtained.

3. Discuss the differences or similarities you identified and answer the following questions:

a) Which substances share similar characteristics?

b) Are similar characteristics related to the type of chemical bond?

c) If they are not related to the type of bond, what is the reason?

d) Is there a lack of information or experimental evidence to classify elements into metals, non-metals, metalloids, and compounds by their type of bond?

e) What tests could you propose and how would you do them?

f) Share some examples of substances that would be difficult to test to determine their composition.

g)With the information obtained, answer:

How is it possible to recognize elements and compounds?

How can their properties be identified?

Why can you predict their chemical comparison and type of bond?
