Only eight problems are on this competitive national chemistry exam. It required the balancing of chemical equations, solving stoichiometry questions, and more. This is part two of three of the national exam. Also available is a...

Here is a unique assigment: compare and contrast ionic and covalent compounds in an extensive data table and then analyze Lewis dot structures in antoher. Three columns are to befilled in: "characteristic or feature," "applies to ionic...

Though there are technically only 13 questions on this exam, they take up six pages and make a thorough assessment of organic chemistry principles. There are plenty of diagrams to label or complete. Emission spectra are displayed for...

Four pages provide plenty of problem solving practice for chemistry whizzes. They answer questions and write electron configurations for ions. They use Lewis dot diagrams to display equations. Covalent bonds are explored. The last half...

As to be expected from the American Chemical Society Olympiad Examinations Task Force, this 60-question test tops the charts in terms of excellence. It consists entirely of multiple choice questions designed to assess a year's worth of...

Sixty multiple choice questions cover the entire gamut of chemistry concepts. This is the local section of the U.S. National Chemistry Olympiad, where your chemistry candidates take a shot at entering the national competition. They...

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

If you need a straightforward and comprehensive organic chemistry exam, check this one out. Chemistry pupils identify functional groups in molecule diagrams, draw a Lewis structure, fill in a table about molecular shape, predict boiling...

Here is a top-notch handout to supply your chemistry class with. It covers valence electrons, Lewis diagrams, the octet rule, and more! Technically it is less of a activity than a detailed explanation of these chemical bonding concepts....

In this chemistry review instructional activity, students classify and name compounds, calculate atomic mass, draw Lewis Dot Diagrams, and determine number of protons for atoms. This instructional activity has 37 fill in the blank, 38...

Get down to basics with these worksheets on the structure of atoms. Challenging young chemists to identify information from the periodic table and create Bohr diagrams and Lewis dot structures for different elements, this...

In this atoms worksheet, students complete a graphic organizer by writing in the number of electrons, valence electrons, electron configuration, orbital box diagram, probability diagram, and Lewis Dot diagram for the given atoms and ions.

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...

Every sort of chemical bond is touched upon during this assignment. Chemistry whizzes identify what type of bond is formed by analyzing chemical formulas or Lewis structure diagrams. Multiple choice questions also ask learners about...

Students write the electron configuration of elements in the ground state. In this chemistry instructional activity, students draw how subatomic particles are arranged in the atom. They construct Lewis dot diagrams of valence electrons.

A flashy PowerPoint includes clear summaries of atomic structure and electronic configuration. Dot and cross diagrams will help viewers learn how to draw an atom. As a result, learners should be more clear how electronic configuration...

Eighth graders identify the three main types of chemical bonds. In this chemistry lesson, 8th graders draw Lewis dot diagrams of elements and determine the bond formed. They create a model water molecule.

All different types of bonding are covered in this PowerPoint, along with details of resulting bond and molecule shapes. The definitions of traditional molecule shapes and characteristics of behavior are very useful to assist in...

Students listen to the teacher introduce VSEPR theory and explain molecular geometry. They use balloons to visualize the shape of orbitals. Students create visuals of molecular orbitals with strings and balloons.

In this chemical compounds worksheet, pupils draw the Lewis structure and "cloud" structures for given compounds. Then students match the Lewis structure with the correct cloud diagrams. This worksheet has 2 problems to solve.

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.

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

In this chemical compounds worksheet, students review the different types of bonding, define the octet rule, and draw Lewis structures (electron-dot diagrams) for given compounds. This worksheet has 7 fill in the blank, 5 short answer...

Name is Bond, covalent bond. Through readings and answering questions, classes explore the different types of chemical bonds, their characteristics, valence shell electron pair repulsion theory, and atomic orbitals.
