Atoms, Ions and Formula Basics Make-up Test

Using a copy of the periodic table, chemistry test takers fill in a chart with element name, chemical symbol, atomic number, atomic mass, and numbers of subatomic particles. They define subatomic particles, draw atom models, explain ions, and determine the number of valence electrons for various elements. This is a well-rounded unit test for the very early high school chemistry learner, or even for middle school physical scientists.
