Give your chemistry students a focused look at valence electrons 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 role do valence electrons play in the chemical properties of an element?", "When two atoms share electrons equally, what type of bond is formed?", and "What is a common result of atoms achieving a full valence shell?"
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 complete NGSS aligned chemistry unit. The unit also covers Atomic Structure Basics, Subatomic Particles Quiz, Electron Configuration, Periodic Table Layout, Predicting Element Properties, and Metals, Nonmetals, Metalloids, 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 NGSS aligned review at any point in the school year. This set is aligned to NGSS standard HS-PS1-1.
