s-Block elements

At the end of this activity, students should be able to:
– write out the electron configurations of the elements in the s–block
– describe the changes in the atomic radii of the s–block elements within groups and periods
– describe the changes in the ionic radii of the s–block elements within groups and periods
– describe the trend in the melting points of the elements in groups 1 and 2
– describe the relationship between atomic structure and the physical properties of elements.
