Atoms, Isotopes, and Ions


Model the sub-atomic particles in atoms, isotopes, and ions.

Use colored chips and the information from a periodic table to model the sub-atomic particles (protons, neutrons, and electrons) in atoms, isotopes, and ions.

  • Model the electron configuration within the electron energy levels.
  • Learn how changing the number of protons, neutrons, or electrons leads to different elements, isotopes, or ions.

Performance Expectations:

HS-PS1-1. Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.

  • Science & Engineering Practices

    Developing and Using Models - Use a model to predict the relationships between systems or between components of a system.

  • Disciplinary Core Ideas

    PS1.A: Structure and Properties of Matter - Each atom has a charged substructure consisting of a nucleus, which is made of protons and neutrons, surrounded by electrons.

  • Crosscutting Concepts

    Patterns - Different patterns may be observed at each of the scales at which a system is studied and can provide evidence for causality in explanations of phenomena.
