In this periodic table worksheet, learners complete a chart with the appropriate element symbol, the atomic mass and the atomic number. They classify elements by their groups and as metals, nonmetals or semi-metals. They also answer two...

In this periodic trends worksheet, students fill out a portion of a periodic table with the atomic number, the atomic radius, the number of shells and the number of outer shell electrons for each element shown. They answer six questions...

In this oxidation numbers worksheet, students determine the oxidation number for given elements and draw Lewis Dot Diagrams. This worksheet has 6 fill in the blank and 11 short answer questions.

This compendious collection of slides leaves no questions when it comes to the concept of atomic size. Thorough and easy-to-read graphs, tables, and graphics explain atomic radii, the shielding effect, the octet rule, isoelectric...

Young scholars use a computer program to study elements and the periodic table. They follow the directions on the computer program, and answer the questions presented. The program is self scoring, and students may print a certificate...

Young scholars perform an experiment that demonstrates acid rain. The chemical effect of acids on metals may take at least five days for the human eye to see, even though the reaction starts as soon as the acid contacts the metal.

In this acids and bases worksheet, students read about what happens when an acid or base is added to water. Students complete 6 short answer questions.

Students will investigate the differences in conductivity of materials, design a variety of complete circuits, and observe the differences between the manner in which light is produced in an incandescent light bulb and an LED.

Study matter in a new way with a cross-curricular assignment for language arts and math. Learners answer five reading comprehension questions after reading a few paragraphs about the periodic table, properties of elements, and how atoms...

Students identify the properties of a magnet. In this physics lesson, students explore the strength of the magnet by testing out how a magnet reacts to various materials. The various objects the students test include paper clips, paper,...

Viewing this slide show prepares your chemistry scholars for chemical nomenclature. Specifically, binary hydrogen compounds and ternary compounds formed from oxyacids are dealt with. One highlight is a useful graphic organizer for naming...

In this science activity, learners identify different parts of one element from the periodic table. Students also complete a chart by writing the appropriate characteristics for metals, metalloids, and nonmetals.

Eighth graders examine the metallic and nonmetallic elements on the Periodic Table. They identify the characteristics of these elements.

Element groups are located in the periodic table by blinking on and off. A slide is then dedicated to each of the groups, explaining which elements are included and what common chemical properties they share. This topic is presented in...

Thirty multiple-choice questions and their answers are provided in this resource. It was written for a general chemistry course and queries test takers on scientific notation, mixtures, chemical symbols, electric charges, Dalton's atomic...

Include a lab about alloys and magnets in your fourth grade science lesson. Young scientists read the necessary background knowledge about alloys, then choose which objects (a screw, a bell, scissors, or coins) will be attracted to...

In this matter worksheet, students compare and contrast chemical and physical properties and explain the relationship between a pure substance and a mixture. Students review the properties of metals and nonmetals. This worksheet has 1...

In this oxidation numbers worksheet, students compare metals and nonmetals, draw Lewis Dot Diagrams, and determine the oxidation number for the given elements. This worksheet has 1 multiple choice, 5 short answer, and 12 fill in the...

In this chemistry worksheet, students complete 15 short answer questions and problems on empirical and molecular formula, naming and writing chemical formula of compounds.

You may want to make a few changes before sharing this slide show with your chemistry class. For one, remove the bright blue swirly background that makes the black font hard to read. Ionic bonds are described with the use of an electron...

In this elements learning exercise, students determine if the given elements are metals or nonmetals. Students give the valence electrons for other elements. This learning exercise has 10 fill in the blank questions.

In this ions learning exercise, students use a charge chart in a textbook to determine the charges of different types of compounds. This learning exercise has 24 fill in the blank questions.

In this ionic bond worksheet, learners read about the transfer of electrons from one atom to another in ionic bonds. They answer seven questions about sodium and chlorine and draw Bohr-Rutherford diagrams to show the bonding between...

In this periodic table worksheet, students will label the atomic number, atomic mass, element name, and element symbol for oxygen. Then students will determine the characteristics of the different groups of elements on the periodic table...
