In this elements activity, students compare the properties of elements in the periodic table such as their atomic radii, valence electrons and ionization energy.

In this naming and writing chemical formulas worksheet, high schoolers are given directions and practice writing simple chemical formulas. They identify positive and negative valence elements, they name nonmetal compounds, they name...

In this elements learning exercise, students review the information that is found on a periodic table including atomic mass, chemical symbol, atomic, number, and electron configuration. This learning exercise has 7 fill in the blank...

This science presentation focuses on the elements in the periodic table. It begins with the parts of an atom, explaining atomic mass and atomic number, valence electrons, and isotopes. Then it moves on to discuss various ways of...

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

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...

In this electron configuration and periodicity worksheet, students answer fifteen questions about periodic trends and they analyze orbital diagrams indicating location of electrons.

In this electron worksheet students complete an orbital diagram and electron configuration using a set of chemicals on the periodic table.

In this atoms worksheet, students complete a graphic organizer by filling in the number of atoms, number of electron pairs, number of long pairs, bond angle, and molecular shape.

As an atomic structure reference and review tool, this handout fits the bill. The first page provides definitions and tables of orbitals, electrons, and energy levels. The second page is an opportunity to practice determining numbers of...

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...

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...

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...

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...

During this hands-on activity, young chemists build molecular models based on the Lewis dot structure before studying valence shell electron pair repulsion theory. 

First, beginning chemists assemble a large periodic table of elements. Then, they play a game in which they roll dice, move a marker along the elements, and collect pennies according to the number of valence electrons of the element that...

In this balancing chemical reactions worksheet, students balance equations, identify electrons gained or lost in atoms and identify the number of atoms of each element for the reactants and products in equations. They also answer 3...

For this molecular geometry learning exercise, learners are given directions and four examples for predicting the geometry of molecules. They determine whether the molecules are pyramidal or trigonal bipyramidal.

In this properties of metals worksheet, students read about the history of metal use and their properties. Students read about metallic bonding and answer three questions about bonding in metals.

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 periodic table instructional activity, students complete a table of elements with their atomic number, atomic mass and symbol. They classify elements by their group name and distinguish between metals, nonmetals, and semi-metals....
