For this electron dot structures handout, new chemists read about electron arrangement and how to draw electron dot diagrams. They complete a chart with the mass number, atomic number, isotope notation, number of neutrons, and Bohr...

After drawing the valence electron distribution of 13 basic elements, there are spaces to draw 18 more complicated molecules.  For each molecule, there is space for a Dot structure and Lewis structure that best describes the...

A short paragraph helps explain how covalent bonds are formed, and then your class will complete the Electron/Dot and Structural diagrams for the molecules given.  The valence diagrams will reinforce understanding. This activity...

A model is worth a thousand words. Young scholars use what they know about the structure of hydrocarbons to build Lewis dot structures and molecular models. Their tasks include multiple bonds, geometric hybrids, and various isomers.

Lewis dot diagrams, Lewis dot structures, and electron dot diagrams are all the same thing. Young scientists learn how to draw Lewis dot diagrams and come to understand how dots and dashes represent valence electrons and ionic or...

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...

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...

In this drawing Lewis structures worksheet, students read about the 5 steps taken to draw Lewis structures for atoms and molecules. These include identifying the valence electrons, placing pairs of electrons between atoms to be bonded,...

For this elements worksheet, students practice drawing electron dot structures for atoms. Students draw the Lewis Structures for molecules with single and multiple bonds plus polyatomic ions. This worksheet has 33 problems to solve.

Explore carbon and bonding with this worksheet. First, class members read a short excerpt about carbon and its characteristics. In response to the reading, they draw an electron dot diagram of carbon as well as diagrams of compounds...

Learners practice drawing Lewis dot structures, build molecules with model kits, and predict molecular shapes using VSEPR theory. The combination of written work and hands-on reinforcement benefits young scientists.

In "The Nature of Covalent Bonding," chemistry hopefuls demonstrate an understanding of various types of covalent bonds, electron configuration, and resonance structures through fill in the blank, true or false, and matching questions....

In this Lewis structures worksheet, students draw molecular structures for twelve molecules. They determine the number of bonds in the molecular formula by following step by step directions given on the worksheet.

In this Lewis dot structure worksheet, students draw the Lewis dot structure and give the electron arrangement and molecular geometry for 27 chemical compounds.

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

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...

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...

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...

In this alkanes worksheet, students complete a table with the chemical formula, the structural formula and the condensed formula of various alkanes given different numbers of carbon atoms. They answer three questions about valence...

This is an online exercise in which chemistry learners answer a series of multiple choice questions about bonding. Topics addressed include ionic and covalent bonds, electronegativity, ions, valence electrons, resonance structure, and...

In this Lewis structures activity, students are given molecules that they must draw Lewis structures for and identify the total number of electrons. They also calculate charges on molecules, determine stability and draw the Lewis...

In this Lewis structures activity, students draw 12 Lewis dot structures for 8 compounds and 4 polyatomic ions using electrons in the outer orbitals to show bonding.

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...

The first nine slides visit the history of our understanding of atoms. The next several outline the structure of atoms. Subatomic particles, electron configuration, and diagramming methods are introduced. This is a neatly organized...
