In this atomic theory worksheet, students review the observations that led to the conclusion of the atom having a positively charged nucleus. Students compare atomic number and mass number and explain how the discovery of subatomic particles and isotopes affected Dalton's atomic theory. This worksheet has 9 problems to solve.

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. 

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.

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.

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.

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.

Atomic Number and Mass

In this atomic number and mass quiz activity, students 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

Pupils 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.

Elements, Atoms, and the Periodic Table

Through three separate exercises, chemistry explorers examine common atoms, the periodic table, and atomic structure. They identify the structural features of an atom, read the periodic table of elements, and calculate the atomic weight of an atom, given its atomic number. Plenty of background information is provided. The easiest way to use this resource would be to get learners online to read it and write their answers on a separate piece of paper to turn in.

Atoms and Chemical Bonding

An online resource, this worksheet 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.
