Model of atom in Structure Of Atom – Class 10 Science Experiment

Chapter Name: Structure Of Atom

Activity Name: Model of atom in Structure Of Atom

Activity Description:

In this activity, students will create a model of an atom based on their previous knowledge. They will be encouraged to arrange sub-atomic particles in different ways with the help of their friends, teacher, and the Internet.

After creating their atomic models, they will carefully observe their own model and those of their friends to answer questions related to the distribution of sub-atomic particles and the differences between atoms of different elements.

Required Items:

1. Paper
2. Pencils or markers
3. Colored pens or stickers (optional)
4. Access to the Internet (optional)

Step by Step Procedure:

1. Gather all the required items and find a comfortable workspace.
2. Start by drawing a basic outline of an atom on the paper. You can represent the nucleus in the center and the electron shells around it.
3. Place the sub-atomic particles (protons, neutrons, and electrons) in the respective regions of the atom.
4. Experiment with different arrangements of sub-atomic particles. For example, you can vary the number of protons, neutrons, or electrons and observe the resulting changes in the atomic model.
5. Collaborate with your friends, teacher, or use online resources to get insights into different atomic models and ways to arrange sub-atomic particles.

Experiment Observations:

• Note the different arrangements of sub-atomic particles and their effects on the overall atomic model.
• Observe the variations in the number of protons, neutrons, and electrons in different atomic models.
• Pay attention to how changing the number of electrons affects the electron distribution in the atom.

Precautions:

1. Handle the paper and drawing tools carefully to avoid accidents or injuries.
2. While seeking help from the Internet, rely on reputable sources to ensure accuracy.

Lesson Learnt from Experiment:

1. Atoms can have different arrangements of sub-atomic particles, leading to variations in their properties.
2. The number of protons in the nucleus determines the element’s identity, as it defines the atomic number.
3. The number of electrons in an atom affects its chemical properties and reactivity.
