Chemistry ideas click fastest with real practice. This set gives your Grade 9-12 class ninety questions on electron shell diagrams, aligned to the same NGSS performance expectation.
Students will answer questions such as "Identify the element with the electron configuration ending in 4s² 3d⁵?", "What is the shape of the 2p orbital?", and "How many unpaired electrons are present in the ground state of a carbon atom?"
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.
