Teaching Atomic Structure Using Cooperative Learning

Individuals in a group of four each take on a different role: atomic number expert, mass number expert, isotope expert, and nuclear atom expert. They teach each other about their area of expertise. As an assessment, a short quiz is provided. 

Distinguishing Between Atoms

Every type of question is used to query young chemists about atomic structure. A vocabulary list tops the page before fill in the blanks, true/false, and matching questions are listed. This is a neatly formatted and pertinent worksheet to assign as review.

Atomic Structure

In this atomic structure worksheet, students review concepts about the components of the atom through 9 short answer questions. Students fill in a table of elements with their subatomic particles, atomic number and mass number.

Calculating the Number of Sub-Atomic Particles in an Atom

In this atoms worksheet, students compare the position, relative charge and relative mass of sub-atomic particles. Students define mass number and atomic number. This worksheet has 2 graphic organizers and 4 short answer questions.

Chapter 4 Worksheet-Part B Atomic Structure

In this atomic structure worksheet, students answer ten questions about the structure of atoms including their subatomic particles, what atomic number and mass number indicate, what isotopes are and what relative mass and relative charge mean.

The Atom, Atomic Number, Mass Number, and Isotopes

Expose your chemistry learners to atomic theory. As they view this PowerPoint, they will learn about subatomic particles, atomic number, and mass number of atoms as well as how isotopes are structured. Throughout this neat and accurate presentation you will find learning-check slides that can be used to assess understanding.

Atomic Number and Mass

In this atomic number and mass quiz worksheet, high schoolers complete an on-line quiz, clicking on questions and matching answers, scoring 1 point for each correct answer. A printed version is available.

Understanding Oxidation Numbers

High schoolers review atomic numbers, positive and negative charges, and the periodic table. They examine the relationships among protons and electrons, location of various elements, electron energy levels, and oxidation numbers.

Atoms and Chemical Bonding

An online resource, this instructional activity has your chemistry learners complete four data tables with information about atoms and chemical bonds. The first table addresses atomic number and mass, as well as numbers of protons, neutrons, and electrons. Table two examines the number of atoms in a chemical formula. Ions are surveyed with a third table in order to prepare learners to understand covalent bonding. Finally, the properties of isotopes are dealt with. Thorough explanations are provided before each chart.

Elements

In this elements worksheet, students determine the atomic number, mass, number, electrons, protons, and neutrons for elements. Students review the electromagnetic spectrum. This worksheet has 1 graphic organizer and 13 multiple choice questions.
