Give your chemistry students a focused look at isotope information in models with ninety questions built for real classroom use, whether you are starting a new unit or reviewing before a test.
Students will answer questions such as "What is the main consequence of an unstable isotope?", "In a model, how can isotopes demonstrate the concept of half-life?", and "If an element has isotopes with mass numbers of 10 and 12, what does the atomic mass represent?"
Because the three worksheets share the same content in three different formats, you can spread them across the week: one for diagnosis, one for practice, and one for assessment, without repeating a single question.
This set is part of a standards aligned chemistry unit. The unit also covers Atomic Number, Mass Number, Isotopes and Average Atomic Mass, Why Atomic Models Changed Over, Quantum Model as a Predictive, Electron Configurations as, and Valence Electrons and Chemical, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 9-12 chemistry classes, and for review at any point in the school year. This set is aligned to Virginia SOL standard CH.2a.
