Periodic trends in the chemical properties of elements

At the end of this activity, students should be able to:
– understand how the electronegativity of elements influences the properties of their compounds
– understand how the oxides of Period 3 elements form, and what their structure and their properties are
– understand how the elements of Period 3 behave in the presence of water
– understand how the chlorides of Period 3 elements form and what their structure is
– understand the chemical properties of the chlorides of Period 3 elements.
