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

The periodic table of elements is a vital tool for all chemistry apprentices and professionals alike. Here is a chance for your beginning chemists to assess their understanding of the periodic table. They list element names, symbols,...

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...

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 instructional activity 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...

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...

In this atoms worksheet, students complete 58 questions about the atomic radius of atoms, the ionization energy, the valence electrons, metals, non-metals and semi-metals and the families of elements.

This PowerPoint provides a complete recap of all the information needed for a unit on elements and the periodic table. The seventy slides cover the basic notation of elements, energy levels and ionization energies. The trends in the...

It's time to whip your chemistry class into shape! Begin your study of molecular geometry with a colorful, 3-D interactive. The resource shows models of linear, trigonal planar, and tetrahedral molecules.

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...

Ninth graders investigate ionic bonding through energy level diagrams. In this ion bonding lesson plan, 9th graders observe demonstrations to show energy level diagrams using magnets to represent the subatomic particles. Students fill...

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...

Lewis dot diagrams, Lewis dot structures, and electron dot diagrams are all the same thing. Young scientists learn how to draw Lewis dot diagrams and come to understand how dots and dashes represent valence electrons and ionic or...

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...

Get back to bonding basics. Science scholars get a chance to show what they know using a simple interactive. Pupils create models of covalent and ionic bonds before answering questions about each interaction. The resource includes a...

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...

In this thermochemistry learning exercise, students indicate whether the given processes are endothermic or exothermic reactions. Students complete the phase change diagram as well as define a given set of vocabulary words. Students...

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...

What makes helium so Noble, anyway? Explore the bonding properties of helium versus those of hydrogen using an interactive resource. Science scholars manipulate atoms of each element and observe changes in potential energy as the atoms...

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

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...
