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...

In 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...

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...

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,...

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 worksheet than a detailed explanation of these chemical bonding concepts....

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...

The first of two worksheets methodically prepares chemistry novices for naming polyatomic compounds. It begins by having them acknowledge the number of each atom contained in a molecule. Then learners list the valence electrons for 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...

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 periodic table and elements instructional activity, students review valence electrons, octet rule, oxidation number, and the difference between metals and non-metals on the periodic table. This instructional activity has 5...

In this Lewis structures learning exercise, students read about drawing Lewis structures and how to identify valence electrons. They draw Lewis structures for eight given compounds.

In this bonding activity, students complete a chart of elements, their symbols, the total number of electrons, the number of valence electrons and the oxidation numbers. They draw Lewis structures for atoms and show the transfer of...

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...

For this VSEPR theory worksheet, learners build models of molecules using styrofoam balls and pipe cleaners to represent lone pairs. Students complete a chart for 12 molecules with valence electrons, Lewis structures, bond angles, lone...

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.

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 metals, non-metals, dot diagrams and ions worksheet, students read about each of these topics and they identify if 8 elements are metals or non-metals, they draw electron dot diagrams for 5 elements, they write the charge of 3...

For this chemistry review worksheet, high schoolers classify and name compounds, calculate atomic mass, draw Lewis Dot Diagrams, and determine number of protons for atoms. This worksheet has 37 fill in the blank, 38 matching, and 3 short...

In this chemical bonds worksheet, students review the different types of bonds, Lewis dot structures, ions, and molecule shapes. This worksheet has 10 matching, 17 multiple choice, and 3 drawing questions.

In this Lewis structures worksheet, students identify and describe what Lewis structures or dot diagrams are and how they illustrate the valence electrons in an outer shell. Then they use a periodic table to determine the numbers of...

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...

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.

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