Context

The Periodic Table is one of the main symbols of Chemistry. It is the way we found to organize all the chemical elements known to man in ascending order of atomic numbers. The periodic table is not just a list of names, but a powerful guide that allows us to predict the chemical and physical behaviors of elements and their compounds.

Metals are one of the largest groups of elements in the periodic table. They include alkali metals, alkaline earth metals, transition metals, lanthanides, actinides, post-transition metals, among others. In our daily lives, we find metals in various forms, such as in construction, household items, jewelry, cars, etc.

Introduction

In this project, we will focus on the analysis of metals, which are essential for the development of a series of technologies we use today. Throughout the project, we will address four main topics: the properties of metals, the location of metals in the periodic table, the classification of metals, and the differentiation between metals and nonmetals. Additionally, by using research and analysis techniques, it will be possible to apply this knowledge in a practical way.

Metals have several interesting properties, such as high electrical and thermal conductivity, metallic luster, malleability, ductility, among others. Each metal has a combination of characteristics that makes it unique and essential for certain applications. These properties can be better understood through the study of the electronic structure of metals.

Not least, metals have a prominent position in the periodic table, which in itself offers a wealth of information. For example, we can see the tendency of alkali metals to be highly reactive and transition metals to form colored compounds.

To conclude, a comparison will be made between metals and nonmetals, as this helps deepen our understanding of metals and provides a broader overview of the periodic table.

Practical Activity

Activity Title: "Metals: Properties, Location, and Applications"

Project Objective

The objective of this project is to research and analyze specific metals from the periodic table, explore their properties, location, examples of uses in daily life, and record the findings in a detailed report.

Detailed Project Description

Groups of 3 to 5 students will select three metals from the periodic table to conduct in-depth research and present their findings in a creative and engaging way.

The groups should research:

1. Properties of the selected metals (such as ductility, malleability, electrical and thermal conductivity, melting and boiling points, etc.)
2. Where these metals are located in the periodic table and their classification (such as alkali metals, alkaline earth metals, transition metals, etc.)
3. How these properties make these metals used in real-life situations.
4. Notable differences between the chosen metals and some selected nonmetals.

Required Materials

1. Chemistry textbooks
2. Internet access to research complementary information
3. Presentation software (PowerPoint, Google Slides, etc.)

Detailed Step-by-Step

1. Form groups of 3-5 students and distribute this project statement.
2. Each group should choose three metals on the periodic table to research.
3. Students should start their research by visiting libraries, using chemistry textbooks, and accessing reliable sources on the internet.
4. Each group should create a presentation to share their findings. The presentation should include a discussion on the properties of metals, an explanation of their location in the periodic table, real-life examples of how these metals are used, and a comparison with some nonmetals.
5. Students should prepare a written report following the format indicated at the beginning of this project.

Project Delivery

Students must deliver, at the end of the project, a presentation and a detailed report that includes:

1. Introduction: Description of the chosen metals, their relevance and application in the real world, and what they learned through the research.
2. Development: Detailed discussion of the properties of metals, location and classification in the periodic table, practical examples of metal use, and differences compared to nonmetals. The research methodology used should be clearly indicated.
3. Conclusions: Recap of the main points, lessons learned, and conclusions about the project.
4. Bibliography: Indication of the sources used for the work such as books, web pages, videos, etc.

It is important that the report writing is synchronized with the presentation and that there is coherence in all the information presented.
