Build atoms and molecules while exploring isotopes, electron configurations and chemical bonds in two interactive learning environments.
Interactive Chemistry: Atoms, Isotopes and Chemical Bonds
Change particles and connections to explore the structure of matter.
Start with composition and connection. Change the protons, neutrons and electrons in an atom to compare elements, isotopes and ions. Then explore molecules and the bonds that connect their atoms. Interactive tools bring these relationships together for comparison.
Shell diagrams, particle colors and bond lines are explanatory representations. Electrons do not follow the fixed circular tracks in a shell picture, and the sizes are not to scale. Consult the original data and model notes when interpreting stability, bonding and electron configurations.
Questions to explore
- What changes when you alter the numbers of protons, neutrons or electrons?
- How does an isotope differ from an ion?
- Which connections appear in a molecule, and what do the lines represent?
