Learning objects Exploring atoms

TLF ID L3125

Explore subatomic particles and how they combine to form atoms and ions. Compare different ways of modelling atoms. Use nuclear symbols to represent different isotopes. Build atoms and ions by combining protons, neutrons and electrons. This learning object is a combination of three objects in the same series.

Educational details
