After studying this unit you will be able to
· Appreciate how the concept of grouping elements in accordance to their properties led to the development of Periodic Table.
· Understand the Periodic Law.
· Understand the significance of atomic number and electronic configuration as the basis for periodic classification.
· Name the elements with Z > 100according to IUPAC nomenclature.
· Classify elements into s, p, d, f blocks and learn their main characteristics.
· Recognize the Periodic trends in physical and chemical properties of elements.
· Compare the reactivity of elements and correlate it with their occurrence in nature.
· Explain the relationship between ionization enthalpy and metallic character.
· Use scientific vocabulary appropriately to communicate ideas related to certain important properties of atoms e.g. atomic/ ionic radii, ionization enthalpy, electron gain enthalpy, electronegativity, valence of electrons.
