This is a tremendous overview of the tiny atom. Journey through the history of human understanding of this basic building block of matter. Examine each of the sub-atomic particles in detail: neutrons, protons, electrons, quarks. Peruse...

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...

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....

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...

Although the directions say to view a PowerPoint, it is not necessary in order to complete this assignment. Six fill in the blank questions survey the periodic table of elements. A chart follows in which, given the element symbol, young...

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....

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

Your young chemists will find these slides very informative. Groups and periods of the periodic table are labeled and described according to the charge. Comprehensive explanations of physical and chemical properties and how they relate...

Prepare a time lapse video of fruit candies acting as atoms moving toward each other to form ionic or covalent bonds. After showing it as a demonstration, have lab groups work together to create a similar video. Over the time period...

Here is a thorough review of chemical bonding! Seventeen problems query chemistry learners about electron configuration and ionic bonding, sharing electrons and covalent bonding. Chemistry masters draw Lewis dot diagrams and answer...

A 12-page midterm exam sample can be given to young scientists in preparation for an exam. This particular installment is geared toward a class that delves into both ecology and chemistry concepts. There is no way to separate the 50...

Sal starts off this video by looking at a traditional chain of carbons and working through the different ways they can be diagrammed.

Using the chemicals that leaked in the Bhopal gas tragedy of 1984, chemists examine covalent bonds. Provide for them the chemical reactions and have them draw Lewis diagrams for the molecules involved. That's about all there is to the...

Guide your chemistry class through the periodic table so that they are able to identify atomic radii, electronegativity, and ionization energy. Give them three metals to place in water to observe reactivity. Teach them to write electron...

In this Lewis structures instructional activity, 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...

In this chemistry worksheet, students complete the chart for each of the listed elements, including the number of protons, electrons, and valence electrons. Then they complete each of the ionic bonds that follows.

For this online vocabulary worksheet, students match 14 definitions to the correct vocabulary term. Students may click the solution button to check answers.
