In this activity students explore the structure and properties of atoms. They construct models of atoms with properties of particular mass and charge; create models of atoms with different stabilities by adding or subtracting neutrons, protons, and electrons to a model atom; and determine that the same element may have varying number of neutrons and these form isotopes.
Students will be able to:
- Explore the probabilistic electron orbital model to help explain where electrons are most likely to be found.
- Explain that all atoms have similar structure, differing only in the number of protons, neutrons, and electrons.
- Build models of atoms and ions and identify patterns in numbers of protons and neutrons in stable nuclei and ions.
- Describe simple patterns in the periodic table.
