Give your chemistry students a focused look at valence electrons and chemical with ninety questions built for real classroom use, whether you are starting a new unit or reviewing before a test.
Among the ninety questions, students will see prompts such as "How many valence electrons does an atom of nitrogen have?", "What is the maximum number of electrons that can occupy a single orbital?", and "Which of the following elements is most likely to form a +1 ion?"
All three worksheets cover the same topic in different question styles. That means you can use one as a pretest, another for practice or homework, and the third as a follow up quiz, without students ever seeing the same question twice.
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 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.2d.
