Description

At the end of this activity, students should be able to:
– define the concept of electronegativity
– explain the electronegativity scale
– describe how electronegativity changes across the periodic table
– explain how the electronegativities of two elements affect the type of bonding between them
– describe the variation of chemical bonding in the halides of the third period elements and the second group elements.
