Undergoing Updates

This content is undergoing updates.

Please check back throughout the year. 

By the end of this section, you should be able to:

  • LG1 - Explain the composition of an atom, detailing its structural components and sub-atomic particles.
     

  • LG2 - Explore the correlation between particles within an atom's nucleus and its atomic mass (mass number).
     

  • LG3 - Elaborate on the connection between the number of protons in an atom, the element type, and the atomic number.
     

  • LG4 - Outline simple electron shell configurations.
     

  • LG5 - Illustrate the connection between electrons in the valence shell of an atom and its overall charge.
     

  • LG6 - Discuss the relationship between the number of neutrons in an atom and the concept of isotopes.
     

  • Review & Consolidation
