The scholarly reviews and opinion pieces provide more classroom-based perspectives on supporting vocabulary development and symbol interpretation.
Alkaline Earth metals Transition metals Have students work with a partner to determine the physical properties of one element in their assigned family: In addition, ask them to name at least two common uses for that element.
Have partners share what they learned with their groups. Discuss and identify common physical properties of elements within their family.
Were elements in that family used in similar ways? Students produced accurate cards for the first 18 elements of the periodic table, including all of the requested information; showed a clear understanding of atomic number, valence Checkpoint vocabulary table, and electron shells by placing their cards in the correct order; worked well within their group to identify several common properties of elements within their assigned family.
Students produced adequate cards for the first 18 elements of the periodic table, including most of the requested information; showed a satisfactory understanding of atomic number, valence electrons, and electron shells by placing most of their cards in the correct order; worked well within their group to identify some common properties of elements within their assigned family.
Students produced inaccurate cards for the first 18 elements of the periodic table, including little of the requested information; showed an unsatisfactory understanding of atomic number, valence electrons, and electron shells and could not place their cards in the correct order; had difficulty working within their group and could identify few or none of the common properties of elements within their assigned family.
A solid substance made by mixing a metal with another substance, usually another metal, to have specific properties that metals alone lack Context: The earliest metalworkers combined different elemental metals in search of the best alloys for weapons and tools.
A substance composed of one type of atom and cannot be chemically separated Context: Antoine Lavoisier was the first to define an element as a pure substance that cannot be broken down.
A column or group of columns in the periodic table; elements in one group have the same number of electrons in the outermost shell Context: Elements in each group share similar chemical properties.
A row of the periodic table; each row corresponds to the number of electron shells in an atom of the elements in that row Context: The elements in the second period each have two electron shells, and the elements in the sixth period have six electron shells.
The structure of the periodic table corresponds directly to atomic structure. This makes the table an invaluable tool for determining the property and behavior of elements and predicting how they will interact.
An element that conducts electricity at higher temperatures, but stops electricity from flowing at lower temperatures Context: The temperature of silicon transistors determines whether they conduct or block electrical currents.
The electrons contained in the outermost shell in an atom of an element; the electrons available for chemical bonding Context: All the transition metals have the same number of valence electrons because electrons are added to interior shells instead of the valence shell.
