2. Recognize the main families of the periodic table, such as halogens, and understand their characteristics.

3. Develop socio-emotional skills such as self-awareness and social consciousness through the study of the periodic table.

Contextualization

Did you know that the periodic table is like a gigantic treasure map, where each element is a valuable clue? 🗺️🌟 It not only helps us understand the matter that makes up everything around us but also reveals the incredible order and harmony of the universe. Imagine discovering how each piece of this chemical puzzle interacts and contributes to life as we know it! Let's explore together this fascinating world of elements and realize that just like in the table, each emotion and social interaction has its own place and importance! 🌈✨

Important Topics

Structure of the Periodic Table

The periodic table is a magnificent organization of chemical elements based on their properties and atomic numbers. It is divided into periods (horizontal rows) and groups or families (vertical columns), where each row indicates the number of electron shells and each column groups elements with similar chemical properties due to electron configuration in the valence shell. This structure allows for a clear and organized view of the elements and facilitates the identification of chemical patterns and trends.

• Periods: Indicate the number of electron shells of the atoms present in that row.

• Groups or Families: Gather elements with similar chemical properties due to the same electron configuration in the valence shell.

• History: Dmitri Mendeleev is recognized for organizing the periodic table in a way that predicted the existence of undiscovered elements in his time.

• Utility: Besides being an essential tool in chemistry, it also serves as a parallel to understand order and structure in our interactions and emotions.

Metals and Nonmetals

The elements of the periodic table are divided into metals, nonmetals, and metalloids. Metals have characteristics such as high conductivity, malleability, and luster, being fundamental elements in industry and daily life. Nonmetals, on the other hand, are more varied in their properties: they can be insulators, solids, liquids, or gases and are essential for life, such as oxygen and carbon.

• Metals: Excellent conductors of electricity and heat, malleable, and commonly used in construction and electronics.

• Nonmetals: Range from insulators to essential elements for life. For example, oxygen is vital for respiration.

• Metalloids: Have intermediate properties between metals and nonmetals, such as the ability to conduct electricity under certain conditions.

• Emotional Relevance: Just as elements have distinct properties, each person has unique emotions and characteristics that enrich their social interactions.

Chemical Families

The families of the periodic table group elements with similar properties. Some of the best-known families are Alkali Metals, Alkaline Earth Metals, Halogens, and Noble Gases. Each family has unique characteristics and plays specific roles in chemistry and industry.

• Alkali Metals (Group 1): Highly reactive, especially with water, including elements such as sodium and potassium.

• Alkaline Earth Metals (Group 2): Less reactive than alkali metals but still quite reactive, including magnesium and calcium.

• Halogens (Group 17): Extremely reactive, especially with metals, forming salts. Examples include fluorine and chlorine.

• Noble Gases (Group 18): Inert gases that rarely react due to their stable electron configuration, such as helium and neon.

• Parallel with Emotions: Each family represents a set of specific characteristics, just as each group of emotions plays a specific role in our lives.

Key Terms

• Periodic Table: Organization of chemical elements based on their properties.

• Periods: Horizontal rows in the periodic table that indicate the number of electron shells of the atoms.

• Groups or Families: Vertical columns in the periodic table that group elements with similar chemical properties.

• Metals: Elements that are good conductors of electricity and heat, usually malleable and shiny.

• Nonmetals: Elements that can be insulators, solids, liquids, or gases, essential for life.

• Metalloids: Elements with intermediate properties between metals and nonmetals.

• Alkali Metals: Elements in group 1, highly reactive.

• Alkaline Earth Metals: Elements in group 2, quite reactive.

• Halogens: Elements in group 17, reactive and form salts.

• Noble Gases: Elements in group 18, usually inert and stable.

To Reflect

• How can the organization of elements in the periodic table be compared to the organization of our emotions and social interactions?

• In what ways can understanding the periodic table influence your ability to make responsible and empathetic decisions?

• Think of a recent situation where you had to work in a group. How can the diversity of roles and characteristics of chemical elements relate to the dynamics of your team?

Important Conclusions

• We understood the basic structure of the periodic table, identifying the organization of elements into metals and nonmetals.

• We recognized the main families of the periodic table, such as halogens, and understood their characteristics.

• We developed socio-emotional skills such as self-awareness and social consciousness through the study of the periodic table.

Impact on Society

The periodic table has an immense impact on society, not only in the scientific field but also in our daily lives. Have you ever stopped to think about how metals are essential in the manufacture of electronic devices we use daily, such as smartphones and laptops? Furthermore, understanding nonmetals like oxygen is fundamental to our health and survival, as we couldn't breathe without them!

Emotionally, the periodic table teaches us the importance of diversity and organization. Each element, with its own characteristics and reactivities, contributes to the balance of the universe, just as each person, with their emotions and uniqueness, contributes to the harmony in their communities. By recognizing the importance of each element and each emotion, we develop respect and empathy, essential for healthy coexistence.

Dealing with Emotions

Throughout the week, choose one element from the periodic table and relate it to an emotion that you feel often. First, recognize this emotion when it arises. Then, understand the causes and consequences of this emotion, reflecting on situations in which it appeared. Name the emotion correctly, whether it's anger, joy, sadness, etc. Express your emotion appropriately, perhaps by writing about it or talking to someone you trust. Finally, regulate your emotions using techniques such as deep breathing or meditation. Write down your reflections and share them in the next class!

Study Tips

• Create a personalized periodic table! Use different colors to mark families, metals, nonmetals, and metalloids. This helps memorize the groups and their characteristics.

• Watch educational videos on YouTube about the periodic table. Visualizing the elements in action can make learning more interesting and fun!

• Form a study group with friends. Each person can choose one family from the periodic table to research and then share with the others. Collaboration helps reinforce knowledge and develop social skills.
