Learning Objectives

• Students will describe the roles of Mendeleev and Moseley in the development of the periodic table by explaining how they arranged the elements in their respective tables.
  

• Students will predict the physical and chemical properties of elements in the table by using periodic law.  

• Students will explain the trends of atomic radii, ionization energy, electron affinity, and electronegativity by using the element’s electron configuration and their understanding of electrostatic forces.

• Students will understand the bonding characteristics of atoms by identifying an atom’s valence electrons from the atom’s location on the periodic table.
