Course Name : S and P block elements

Code (credit): CUTM1473 (3-2-1)

Objectives

  • To identify the common physical properties of metals and non- metals and explain how their uses relate to these properties.
  • To explore in depth specialized areas of chemistry of materials, including ores, metals, acids and bases and to understand how metals are extracted from their ores.
  •  To understand the trends in properties and reactivity of the s, p-block elements and noble gases.
  •  To become familiar with some of the roles of inorganic polymer and its applications in day to day life.

Learning Outcomes

  • Discuss fundamental aspects of main group chemistry, including trends in oxidation states, periodic properties and complex formation tendency.
  • The resulting knowledge primarily serves the success of students pursuing research in the field of chemical metallurgy.
  • To familiar with a variety of different methods for synthesizing inorganic materials and principles of inorganic polymer synthesis.
