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...

There are 66 objectives to be covered by upcoming chemists if they complete this two-chapter assignment. It encompasses all of the information needed to deal with covalent bonds and molecular geometry. Colorful diagrams display the...

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...

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 learning exercise than a detailed explanation of these chemical bonding...

Biochemistry scholars will be well prepared for an exam on biomolecules after completing this concise assignment! There are 75 short-answer questions about the chemical makeup, functions, and relationships between organic molecules....

Newbies to chemistry will be enriched when completing this worksheet. It gets them to explain the subatomic particles and their charges, ions, and valence electrons. On the second page they complete a chart of the numbers of protons,...

Two presentations are contained in this resource designed to give biology learners a foundational understanding of chemistry. The first journeys through the basics: atomic structure, the periodic table, isotopes, and valance electrons....

Bond with your chemistry learners through a presentation on chemical bonding. This attractive and informative collection of slides walks beginning chemists through types of molecular bonds, orbital shapes, how to draw Lewis structures,...

Emerging chemists complete the table of electron levels, write electron configurations, and draw Lewis structures for a variety of atoms on this worksheet. Though there is a note about accessing a classroom website on the upper right...

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...

First, high school chemists fill in a chart for seven elements to show the numbers of protons, electrons, valence electrons, and electrons needed to full the outer shell. Then combinations of elements are listed. Instructions say simply...

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...

The first four of these six pages query advanced biology learners all about bacteria. Different reproductive means, life cycles, symbioses, and methods of genetic diversity are addressed. Questions consist of short answer type and...

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 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...
