Here are the general procedures for carrying out a practical on the reactivity of metals and non-metals:
1. Gather the materials and equipment needed for the experiment. This includes various metals of different reactivity (e.g. copper, zinc, magnesium), non-metals (e.g. sulfur, carbon), test tubes, Bunsen burner, tongs, safety goggles, and a litmus paper.
2. Place each metal in its own labeled test tube and non-metals in separate labeled test tubes.
3. Perform a series of experiments to observe the reactivity of metals and non-metals. For metals, one common experiment is to add dilute hydrochloric acid or sulfuric acid to each test tube and observe the reaction. More reactive metals will produce effervescence (bubbles) and release hydrogen gas. For non-metals, you can heat them using a Bunsen burner and observe any changes, such as color or odor.
4. Ensure safety precautions are followed throughout the experiment. Wear safety goggles to protect your eyes and handle the test tubes with tongs to avoid direct contact with the chemicals.
5. Record your observations in a table or notebook. Note the reactivity of each metal and non-metal by writing down the presence or absence of a reaction, effervescence, color changes, or odor.
6. Test the pH of the solutions in the metal test tubes using litmus paper. More reactive metals will produce acidic solutions, while less reactive metals will produce neutral or slightly basic solutions.
7. Analyze and interpret your results. Compare the reactivity of metals and non-metals based on your observations. Note any patterns or trends in the reactivity of the substances.
8. Clean up all materials and dispose of any chemicals properly according to your school or laboratory guidelines.
Note: The specific procedures may vary depending on the experiment or the curriculum. Always follow the instructions provided by your teacher or the experiment manual.

Create a practical lesson plan for the reactivity of metals and nonmetals
Lesson Plan: Reactivity of Metals and Non-Metals
Grade Level: 9th-10th Grade
Subject: Chemistry
Objective:
1. Students will understand the concept of reactivity and how it relates to metals and non-metals.
2. Students will observe and analyze the reactions of different metals and non-metals when exposed to certain substances.
3. Students will demonstrate understanding of the reactivity trend among metals and non-metals.
Materials:
- Various metals (copper, zinc, magnesium)
- Non-metals (sulfur, carbon)
- Test tubes
- Dilute hydrochloric acid or sulfuric acid
- Bunsen burner
- Tongs
- Safety goggles
- Litmus paper
- Notebook or table for recording observations
Procedures:
Introduction (5 minutes):
1. Begin the lesson by asking students what they know about metals and non-metals.
2. Discuss basic properties of metals and non-metals, including conductivity, malleability, and appearance.
3. Explain that the reactivity of metals and non-metals can differ and can be observed through various experiments.
Activity 1: Reactivity of Metals (20 minutes):
1. Show students the metals and non-metals you will be working with.
2. Divide students into small groups and assign each group a metal.
3. Distribute labeled test tubes with dilute hydrochloric acid or sulfuric acid to each group.
4. Instruct students to carefully add the acid to their test tubes containing their assigned metal and observe any reactions.
5. Have students record their observations, noting whether there is effervescence (bubbles), color changes, or any other evidence of a reaction.
6. Provide litmus paper for students to test the pH of the resulting solution in each test tube.
7. Facilitate a class discussion on the reactivity trends among the different metals based on observations and pH results.
Activity 2: Reactivity of Non-Metals (20 minutes):
1. Show students the non-metals you will be working with.
2. Repeat the grouping process and assign each group a non-metal.
3. Instruct students to heat their assigned non-metal using a Bunsen burner and observe any changes in color or odor.
4. Have students record their observations for each non-metal.
5. Facilitate a class discussion on the reactivity patterns observed among the non-metals.
Conclusion and Wrap-up (10 minutes):
1. Summarize the observations and results from both activities and highlight the reactivity trends found among the metals and non-metals.
2. Engage students in a discussion on the practical applications of understanding reactivity in everyday life.
3. Assess students' understanding by asking them questions about the concepts learned during the experiment.
4. Assign a follow-up activity or homework that reinforces the concept of reactivity.
5. Clean up the materials and ensure safe disposal of any chemicals used during the experiment.
Note: Adjust the timing and level of detail in the discussion and instructions according to the learning pace and grade level of the students. Always prioritize safety measures and follow the guidelines provided by your school or district for conducting practical experiments.
