Written by Adi Ackerman, Head Teacher
Atoms are made of protons, neutrons and electrons, and they bond into molecules or extended structures. There are 14 sheets for 8th grade here, each with an answer key. Students draw Lewis dot diagrams, shared electron pairs, Bohr models of ions and ball and stick models, compare ionic, covalent and metallic substances and classify molecules and extended structures. Other sheets cover how subatomic particles were discovered, isotopes, nuclear notation, alpha, beta and gamma radiation and half life. Six of the sheets practice MS-PS1-1.
