The rows are called “Periods”

The larger of the two numbers in the box is called
the “Mass Number” or “Relative Atomic Mass”

The smaller of the two numbers in the box is called

Task
Sort the different elements in to groups.
Write down each group and the property you
grouped the elements by.
 Write a reason for each of you choices.
 Look at a copy of the periodic table. Use the
table and other sources of information to fill in
the missing information on your element data
cards.
 Compare the elements in the groups you came
up with to the table that scientists around the
world have agreed on. Do you notice any links
between the groups you made up and where the
elements are on the actual periodic table?
