Students predict the shape of molecules using VSEPR theory. For this chemistry lesson, students differentiate a polar and nonpolar molecule. They discuss why water's polarity is very important.

Eighth graders identify the types of bonds elements form. In this chemistry lesson, 8th graders represent valence electrons with dot structures. They draw and label different atoms.

In this chemical compounds worksheet, students calculate moles, molar concentration, and volume of given compounds. Students balance equations, give the formula and charge of polyatomic ions, and draw Lewis electron dot structures. This...

For anyone learning or teaching chemistry, nothing beats a free and interactive periodic table of the elements. Peruse the elements while learning about atomic number and mass, melting and boiling points, and many other properties of...

Students read an article identifying any new vocabulary words they are unfamiliar with. Using the text, they discover antonyms, synonyms and word families. They answer comprehension questions and review the vocabulary to end the lesson.

In this chemistry review worksheet, students give atomic symbols for given atoms, calculate moles, determine empirical formulas, and balance chemical equations. This worksheet has 1 drawing, 9 fill in the blank, and 12 word problems.

In this molecular geometry and VSEPR learning exercise, students find bond angles, hybridization, determine polarity and draw orbital box diagrams of molecules. They determine molecular geometry and bond angles of given molecules and...

In this ionic compounds worksheet, students identify the number of electrons gained or lost in ions, they show that transfer of electrons in ionic compounds and they write balanced ionic compounds given ions. They answer 4 questions...

High schoolers quantify the relationship between moles and mass. They comprehend that ammonium nitrate is used as a fertilizer and an explosive. Students study the chemistry of ammonium nitrate and consider the advantages and...

In this decimal addition and subtraction for grade 3 worksheet, 3rd graders answer 10 multiple choice questions, not interactively,  with the answers available online.

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...

Tutorial outline weaves together resource links which instruct the learner in drawing Lewis dot structures. A pre- and post-quiz are provided, as well as visuals, questions with immediate feedback, and a reading list to help students...

Students draw and interpret Lewis dot diagrams for individual atoms and both covalent and ionic compounds.

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."

This lesson will demonstrate how to draw a Lewis dot diagram for a molecule that has single bonds. It is 2 of 2 in the series titled "Lewis Dot Diagrams of Molecules - single bonds."

An excellent lesson on writing Lewis structures. Examples shown include ammonium ion, carbon dioxide and the carbonate ion.

Find out how molecular bonding is represented by Lewis dot diagrams.

Students will use colored fruit loops to organize valence electrons to develop and master the basics of Lewis Dot diagrams. They will develop processing and critical thinking skills and also master a model of bonding.

This audio book, narrated by author Mark Bishop, details the steps to drawing Lewis dot structures. Also find links to power points and chapter maps about other chemistry topics.

This lesson will demonstrate how to draw a Lewis dot diagram for a molecule which has a double bond. It is 2 of 2 in the series titled "Lewis Dot Diagrams of Molecules: Double Bonds."

This lesson will demonstrate how to draw a Lewis dot diagram for a molecule which has a triple bond. It is 2 of 2 in the series titled "Lewis Dot Diagrams of Molecules: Triple Bonds."

[Free Registration/Login may be required to access all resource tools.] Students will use their knowledge of covalent bonds, and apply that to drawing Lewis dot structures to represent compounds.

This lesson include biographical information, but it focuses on the concepts behind the "dot diagrams" that Lewis introduced.

This slide presentation contains a few slides that will be useful for students learning to write Lewis structures. A discussion of multiple bonds is included, and clear examples are shown.
