Mixtures, Elements and Compounds

Structure of the atom - Structure of an atom
Structure of the atom - Atomic number and mass number
Structure of the atom - Illustrating atomic number and mass number
Structure of the atom - Rules of electron arrangement
Structure of the atom - Drawing electron arrangement diagrams

By the end of the lesson, the learner should be able to:

- Define the term atom and describe its basic structure
- Identify the nucleus, energy levels, protons, neutrons and electrons in an atom
- Appreciate the importance of understanding atomic structure as the foundation of chemistry

In groups, learners are guided to:
- Discuss what an atom is and its role as the basic building block of matter
- Draw and label a diagram showing the nucleus and energy levels of an atom
- Search digital resources for information on atomic structure and share findings with classmates

What makes up the basic building block of all matter?
