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...

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...

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...

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 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 bonding activity, students read about the attraction of electrons to the protons in other atoms to gain, lose or share electrons in bonds. Students answer eight questions about bonding using the reading and their knowledge of...

In this atoms worksheet, students determine the energy difference between levels and draw diagrams of the different types of orbitals. Students determine the ground state electron configuration for given elements. This worksheet has 14...

Young scholars write electron configurations and identify groups.  In this investigative lesson students use valence electrons to draw electron dot structures. 

Thorough explanations of the trends in the periodic table of elements make up the majority of this handout. Atomic and ionic size, ionization energy, electron affinity, and electronegativity are presented before giving chemistry...

Chemists compare the electronegativity, ionization energy, electron affinity, and ionic radius of different elements. This worksheet is composed of 11 multiple choice questions, and 8 written explanations. Critical thinking skills are...

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...

What does it look like when two atoms bond? Mol-e-COOL! Aspiring chemists observe the interaction between two atoms forming a bond in an easy-to-use interactive. Individuals move atoms closer together and observe changes in attraction...

Does your class understand how things become charged? Are you positive? Before negative grades emerge, assign a fun interactive! The first in the five-part Static Electricity series contains three levels of charge-related questions and...

Teach your class to think of electrons as tiny packets of energy that travel in waves. Through a short video and diagram, participants see how electrons are located around the nucleus of an atom. They then get into groups and try to...

In this chemistry worksheet, learners complete the chart for each of the given elements by naming the number of protons, electrons, Valence electrons, and the electrons used to fill the outer shell. Then they complete each covalent bond...

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....

An engaging activity enlightens young chemists in this lesson on atomic structure. They play musical chairs through a series of concentric circles that represent electon orbitals. A laundry basket in the middle holds the protons and...

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 is one cool resource for teaching about polarity! Chemistry scholars observe electron distribution and molecular shape as they select different non-metals and form bonds. The interactive offers two views, surface charge and electron...

In this elements worksheet, students write the complete electronic configuration and the number of valence electrons for elements. Students classify elements based on their electronic configuration. This worksheet has 5 problems to solve.

In this elements worksheet, students read how the elements are organized in periods and groups in the periodic table. Students use the periodic table to find the valence electrons and calculate molecular mass. This worksheet has 20 fill...

For this molecular shapes worksheet, students read about how to predict molecular shapes in molecules based on the number of electron pairs and the VSEPR theory. Students are given twelve molecules, they draw the Lewis structures 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.
