This is the third activity worksheet in a series designed to help students practice calculating the number of protons, neutrons, and electrons in a given neutral atom or charged ion. The worksheet provides students with a reference guide for reading element squares and identifying an atom's atomic number, symbol, name, and atomic mass. A reference guide is also included for calculating the number of each atomic part in a given atom or ion. Students are asked to fill in the number of protons, neutrons, and electrons for the atoms and ions listed in the chart. This worksheet is designed to be used for practice in middle school, high school, and higher education chemistry classes as students study the periodic table and the characteristics of various elements. It can be used as a homework assignment or in-class activity, and can also be incorporated as a graphic organizer for an interactive notebook entry. This document includes a 1-page worksheet and a 1-page answer key, created by Heather Carmody.
