The Periodic Table has changed over time
That was then… This is now…This is a picture of
Dmitri Mendeleev's 1st draft version for the periodic table (click image to enlarge)
This is an example of how the periodic table looks like today. (click image to enlarge)

The FounderThis is a picture of a young Dmitri Mendeleev, also known as, the father of the periodic table! (More Info.)
More about Mendeleev and his periodic tableScientific benefits of Mendeleev's tableMendeleev predicted the discovery of other elements and left space for these new elements, namely eka-silicon (germanium), eka-aluminium (gallium), and eka-boron (scandium). Thus, there was no disturbance in the periodic table. He pointed out that some of the then current atomic weights were incorrect. He provided for variance from atomic weight order. Shortcomings of Mendeleev's tableHis table did not include any of the noble gases, which were discovered later. These were added by Sir William Ramsay as Group 0, without any disturbance to the basic concept of the periodic table. There was no place for the isotopes of the various elements, which were discovered later.http://en.wikipedia.org/wiki/File:Mendeleev_Table_5th_II.jpg

Discussion Questions How are the elements
organized in the periodic table?
What are some of the properties of the elements by which they can be organized?
How was Mendeleev's periodic table different from those of other chemists of the time?
What kinds of information about the atomic structure of an element can you learn from the periodic table?
What can you tell about the elements from the way they are ordered in the table?
How can the periodic table help you predict how atoms of different elements might combine?
Describe one type of chemical bond - metallic, ionic, or covalent.
Air is approximately 21 percent oxygen gas (O2) and 78 percent nitrogen gas (N2). Can you tell from the information in the periodic table why helium balloons float in air?
Which would you predict would be the heaviest and the lightest materials that would be good conductors of electricity?
If carbon monoxide leaked into your house, would you predict that it would float to the top of the room or stay near the floor? What about carbon dioxide?
