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.
How to use the Periodic Table to identify metals, semimetals,
nonmetals, and halogens.
How to use the Periodic Table to identify alkali metals, alkaline
earth metals and transition
metals, and
trends in ionization energy, electronegativity, and the relative sizes of
ions and
atoms.
How to use the Periodic Table to determine the
number of electrons available for bonding.
