8th Grade The Periodic Table Worksheets

Ages 13-14 · Free previews · Print-ready PDFs

Written by Adi Ackerman, Head Teacher

The periodic table arranges the elements by atomic number so that elements with similar properties line up in groups. There are 9 sheets for 8th grade here, each with an answer key. Students graph first ionization energy and atomic mass, place element discoveries on a timeline, fill in periods 5 and 6 on a blank table and calculate average atomic mass from isotopes. Other sheets cover valence electrons, ion charges and trend arrows, a bonding review quiz and naming ionic compounds from clues.
