This resource turns atomic number, mass number into a complete, ready to use review for Grade 9-12 chemistry, covering the same idea from three different angles.
Students will answer questions such as "Which of the following represents an isotope of carbon with 7 neutrons?", "What is the mass number of an atom with 15 protons and 16 neutrons?", and "What is the mass number of an atom with 9 protons and 10 neutrons?"
Each worksheet reviews the same core ideas from a different angle. Use them across a week or unit so students see the material three times without it ever feeling repetitive.
This set is part of a standards aligned chemistry unit. The unit also covers Isotopes and Average Atomic Mass, Why Atomic Models Changed Over, Quantum Model as a Predictive, Electron Configurations as, Valence Electrons and Chemical, and Excited Electrons and Observable, 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.
