The periodic table of the elements

At the end of this activity, students should be able to:
– state the criteria for classifying the elements in the periodic table
– state the group to which a given element belongs on the basis of its number of valence electrons, and vice versa
– state the period to which a given element belongs on the basis of its number of electron shells, and vice versa
– state the block to which a given element belongs – s, p, d or f – on the basis of its electron configuration
– give the electron configuration of an element on the basis of its position in the periodic table, and vice versa.
