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 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...

What a cute approach to chemical bonding! Atoms all have human names and are attending at a dance. Who will pair up with whom? By reading the characteristics, and not the element name, chemistry whizzes figure out the bonding pairs....

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 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,...

In this periods, groups, valence electrons and masses worksheet, students are given information about all these components of the periodic table. Students identify 4 elements in specific periods and groups, they find the valence...

At the top of the page are a reading passage and colorful diagram that depicts the tug-of-war that occurs between bonding molecules due to electronegativity. High school chemists fill in a chart with electronegativity values, the...

Four activities immerse beginning chemists into the world of elements. They examine the periodic table, use cobalt hydroxide to learn about chemical formulae and valence electrons. Also, they name binary compounds and examine the...

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....

The periodic table of elements is a vital tool for all chemistry apprentices and professionals alike. Here is a chance for your beginning chemists to assess their understanding of the periodic table. They list element names, symbols,...

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...

Why is water always so bent out of shape? Scholars investigate the molecular geometry of the water molecule using a 3-D resource. The interactive features options such as rotation and the ability to view electron pairs.

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...

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...

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...

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...

Ninth graders investigate ionic bonding through energy level diagrams. In this ion bonding lesson plan, 9th graders observe demonstrations to show energy level diagrams using magnets to represent the subatomic particles. Students fill...

What makes helium so Noble, anyway? Explore the bonding properties of helium versus those of hydrogen using an interactive resource. Science scholars manipulate atoms of each element and observe changes in potential energy as the atoms...

An organized table charting the different types of chemical bonds arrays this resource. The octet rule, ionization energy, and the naming of compounds are also reviewed. Young chemists answer review questions in multiple choice fashion....

How are chemical bonds similar and how are they different? Provide your young chemists with the resources to more thoroughly understand the concepts of ionic and covalent bonds. Pupils research these topics, diagram examples of each...

Neatly organized and easy to read, this chart summarizes five different molecular shapes: linear, trigonal planar, tetrahedral, trigonal bipyramidal, and octahedral. It associates shapes with electron pairs and atom arrangement and lists...

Show your chemistry class that there's much more to covalent bonding than sharing electrons! Pupils manipulate atoms of hydrogen, oxygen, and carbon to observe the energy of bond formation using a well-rounded interactive. The resource...

Get back to bonding basics. Science scholars get a chance to show what they know using a simple interactive. Pupils create models of covalent and ionic bonds before answering questions about each interaction. The resource includes a...
