ORGANIZING ELEMENTS
Introduction: In this activity you will develop a “min periodic table” based on twenty elements. Your table will be made
by grouping elements that share similar physical and chemical properties. To complete the table, you will need to use
the table of properties provided (Table #1 & #2) or interpret results of experiments or demonstrations.
PART ONE:
PHYSICAL PROPERTIES
Using tables 1 & 2 circle the elements that have/are
(a)
(b)
(c)
(d)
Melting points above 2,000 C
Boiling points above 700 C
Densities above 1.7 g/cm3 in the solid state
Gases at 20 C
CHEMICAL PROPERTIES
Using tables 1 & 2 and the periodic table, circle the elements that are/do
(e) Metals
(f) Nonmetals
(g) Combine with hydrogen to form gaseous or liquid hydrides
USE THE RESULTS OF THE EXPERIMENT “CHEMICAL PROERTIES OF SOME METALS” TO COMPLETE ROWS (h) and
(i).
(h) React with water to produce hydrogen gas
(i) React with acids to produce hydrogen gas.
USE YOUR OBSERVATIONS OF DEMONSTRATIONS TO COMPLETE ROW (j)
(j) Able to form oxides which are acidic when dissolved in water
(k) Able to form chlorides with boiling points above 1,000 C and a formula of XCl
(l) Able to form chlorides with boiling points above 500 C and a formula of XCl2
(m) At one time were thought to form no compounds and are called noble gases.
PART TWO:
Using the table of 20 elements you have just circled, place the elements you have determined to have similar
properties into groups. Elements should share at least (preferably more) three properties in common to form a group.
Try to have the groups of elements be as exclusive as possible (i.e: attempt to have as many groups as possible with the
fewest number of elements in each group). For each grouping of elements you develop, list the properties they share in
common that caused you to place them together.
