The periodic table is a table of the chemical elements in which the elements are arranged by order of atomic number in such a way that the periodic properties (chemical periodicity) of the elements are made clear. The standard form of the table includes periods (horizontal rows in the periodic table) and groups (vertical columns). Elements in groups have some similar properties to each other. As a chemist, it is important to have a basic grasp of the properties that make each column/group/family unique.
Procedure:
Obtain a copy of the blank periodic table.
Develop a color code for each of the families listed below (atomic number of members is provided). Color in the family on the periodic table and the title of the box for that family.
Hydrogen Family – 1
Alkali metals – 3, 11, 19, 37, 55, 87
Alkaline earth metals – 4, 12, 20, 38, 56, 88
Transition metals – d block and 13, 31, 32, 49, 50, 51, 81, 82, 83, 84
Rare earth metals – f block
Boron Family – 5
Carbon Family – 6, 14
Nitrogen Family – 7, 15, 33
Oxygen Family (Chalcogens) – 8, 16, 34, 52
Halogens – 9, 17, 35, 53, 85
Noble gases – 2, 10, 18, 36, 54, 86
Use the internet to complete the following tasks
Draw the ‘metal vs non-metal line’ and use two arrows to show the direction of metals and non-metals. Put a small star in the corner of each of the metalloids
Fill in the missing information at the bottom of the page
Remember that the period tells you the number of clouds/layers of electrons that the elements in that row have. Number the periods on your table (lines provided).
For each of the following statements, identify which family is being described and write the statement in the corresponding information box.
1 valence electron Includes Al –most abundant metal in the earth’s crust
2 valence electrons Includes C (element of life) – has its own branch of chemistry! C can bond with just about anything but is not dangerously reactive
