This resource turns electron configuration into a complete, ready to use review for Grade 9-12 chemistry, covering the same NGSS standard from three different angles.
The set includes questions like "Which of the following represents the electron configuration of a chlorine atom?", "What does the principal quantum number (n) indicate?", and "Which subshell is filled after the 5s subshell?"
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, Periodic Table Layout, Predicting Element Properties, Metals, Nonmetals, Metalloids, and Valence Electrons, 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.
