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...

It's electronic! Pupils uncover elements and their electron configurations as they explore mass, groupings, correct charges, and sliding theory. Young scientists learn creative ways to remember various elements and correctly...

Nothing says organization quite like a table. The third instructional activity in a six-part Mixtures and Solutions unit teaches young scientists about elements and the periodic table. They learn how the periodic table is organized and...

How did Rutherford determine that the nucleus was the center of an atom? Take a look inside the famous Gold Foil Experiment with an interesting interactive. Learners fire a beam of alpha particles at a nucleus containing variable...

In this electron worksheet, students read about how atoms lose and gain electrons and how they become ions. They are given a table with nine elements and they give the electron configuration, the number of electrons, the number of...

Atomic theory, a periodic table, and a place to practice making atom models without having to draw every proton, neutron, electron, and orbital! This resource is colorful, visually pleasing, and easy to use. 

All you will find here is a simplistic chart of 17 elements (hydrogen is repeated) for chemistry beginners to fill in. They list atomic number, mass, and the numbers of protons and electrons. There are three critical thinking questions...

If you are not part of the solution, then you are part of the precipitate. The presentation covers solutions, suspensions, solubility, dissociation, and acid/base reactions. This is the 19th lesson in a series of 26.

Simple in format and standard in content, this resource is an assessment of your beginning chemists' grasp of the atom. Using a periodic table of elements, they fill in a chart of missing chemical formulas, atomic masses, and numbers of...

Multiple representations of the varying theories of atomic structure. With these pictures and some background of the theories and scientific figures surrounding them, your class will develop a better understanding of scientific history...

In this chemistry worksheet, students fill in the chart for question one. The chart is filled out examining the mass, protons, electrons, and neutrons for specific atoms.

Dispel the misconception that atoms are always little round balls! Illustrate changes in the electron cloud with an entertaining interactive. Pupils push and pull on the cloud by altering the charge on plates located on either side of...

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...

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...

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...

Shock your physical science class using this video to teach the basics of static electricity. Electricity is defined,and electrons are differentiated from protons on an atom model. The use of hydropower and wind are explained as ways of...

In this elements instructional activity, high schoolers 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...

Eighth graders discuss and write about what led up to the discovery of the atom. Students label proton, nucleus, electron, and neutron in their notes. Students take notes on electron shells and how different atoms have different...

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

In this atom worksheet, learners learn about the scanning tunneling microscope and answer questions about its use, how it works and its ability to see electrons in atoms.

Every type of question is used to query young chemists about atomic structure. A vocabulary list tops the page before fill in the blanks, true/false, and matching questions are listed. This is a neatly formatted and pertinent activity to...

In this ions activity, learners complete a graphic organizer by filling in the number of protons and electrons plus the charge of the given ion.

Investigators use indirect evidence to guess what is occupying a sealed box. You could also use a set of plastic Easter eggs to encase the unknown items. Another terrific activity involves having young scholars drop a pencil on a sheet...

Excited atoms lead to exciting lessons! Learners use heat and light to excite both atoms and molecules. They display their learning in the form of Bohr models depicting the excited state of the atoms.
