In this electron configuration and periodicity worksheet, students answer fifteen questions about periodic trends and they analyze orbital diagrams indicating location of electrons.

Students write electron configurations and identify groups.  In this investigative lesson students use valence electrons to draw electron dot structures. 

Students demonstrate their understanding of a chemical process.  In this exploratory instructional activity students create a clay animation that shows how a specific type of chemical bond. 

In this chemistry, students draw the Lewis structures of 20 covalent compounds. They demonstrate how the lone pairs are distributed in the molecule.

Students observe the periodic table and draw the Lewis Dot Diagram.  For this investigative lesson students construct information on several elements including the Lewis Dot Formation and take a quiz on the information they...

In this ionic bonding activity, students review the characteristics of ionic bonding, draw Lewis dot diagrams for elements, and write the chemical formula for ionic compounds. This activity has 8 drawings, 14 fill in the blank, and 6...

Students cuminate their study of molecular structure and bonding with this activity.

Eighth graders define a planet by the orbit around the sun, have a large enough gravitational force to hold a sphere shape and needs to clear the neighboorhood of it own orbital zone. They describe comets, meteoroids, meteor, meteorites...

In this ionic bonding worksheet, students observe diagrams about ionic bonds and crystal formation. They answer 37 short answer questions about the properties of monatomic ions, polytomic ions and write correct formulas.

Learners are introduced to the periodic table. They find the common trends among the electron configurations and the names of certain groups of the table. Students explore the atomic mass, atomic number, mass number, mass and charge...

In this chemistry worksheet, students examine the oxidation state in order to apply it in the laboratory setting. The sheet includes in depth background information.

Test your class with a physical science quiz. Learners explain chemical processes, name compounds, write formulas for chemical compounds, balance equations, and more. 

Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...

In this compounds instructional activity, students review the rules for naming compounds. Students apply these rules by writing the chemical name or formula for the 50 compounds given.

After a short introduction, chemistry aces get right into drawing electron dot diagrams for covalent bonds. There are only three questions to answer, so this is not a comprehensive worksheet. It can be used when introducing your class to...

In this chemical bonding worksheet, students read about the invisible killer, dihydrogen monoxide. Students read about the products it is used in and the problems it causes to the environment. Then students complete 19 short answer...

In this atomic theory worksheet, students use Planck's constant, Rydberg constant, and Avogadro's number to complete 20 multiple choice questions.

In this 9th grade science review worksheet, high schoolers complete 63 true or false questions on topics such as atomic notation, isotopes, covalent bonds, Ohm's law, and electric circuits.

This lesson will demonstrate how to draw a Lewis Dot diagram for elements. It is 4 of 4 in the series titled "Lewis Dot Diagrams of Elements."

Identify the number of valence electrons of given elements.

Short slide show provides basic information about drawing Lewis dot structures for covalent compounds. Starts with anatomy of the atom, and then shows the relationship between atomic particles and the Periodic Table of Elements. Offers...

[Free Registration/Login may be required to access all resource tools.] Valence electrons, their variation in the periodic table and relation to reactivity and electrical conductivity of elements.

A short assessment to see if you understand valence electrons in specific elements.

A slide show presentation which demonstrates how to identify the number of valence electrons an element has based on its location on the periodic table.
