Atomic and Molecular Structure
1. The periodic table displays the elements in increasing atomic number and shows how periodicity of the physical and chemical properties of the elements relates to atomic structure. As a basis for understanding this concept:
- Students know how to relate the position of an element in the periodic table to its atomic number and atomic mass.
- Students know how to use the periodic table to identify metals, semimetals, nonmetals, and halogens.
- Students know how to use the periodic table to identify alkali metals, alkaline earth metals and transition metals, trends in ionization energy, electronegativity, and the relative sizes of ions and atoms.
- Students know how to use the periodic table to determine the number of electrons available for bonding.
- Students know the nucleus of the atom is much smaller than the atom yet contains most of its mass.
- * Students know how to use the periodic table to identify the lanthanide, actinide, and transactinide elements and know that the transuranium elements were synthesized and identified in laboratory experiments through the use of nuclear accelerators.
- * Students know how to relate the position of an element in the periodic table to its quantum electron configuration and to its reactivity with other elements in the table.
