The periodic table of the chemical elements is a tabular method of displaying the chemical elements. Although precursors to this table exist, its invention is generally credited to Russian chemist Dmitri Mendeleev in 1869. Mendeleev intended the table to illustrate recurring trends in the properties of the elements. The layout of the table has been refined and extended over time, as new elements have been discovered, and new theoretical models have been developed to explain chemical behavior.

The Periodic Table is classified into this categories:
Metals

Metalloids (between Metals and Non-metals)
Nonmetals

Sub-categories:

Under Metals:

Alkali metals
Alkaline earth metals
Inner transition elements
Transition elements
Other metals

Under Non-metals:
Other nonmetals
Halogens
Noble gases

And lastly, A category called Unknown :D

Also, here's a video on the Periodic Table...complete with lyrics!

Actually there are two videos. The first shows the song with all the big words. The second video shows where the elements are in the Periodic Table.

Sorry I cannot place it here...because there's a problem with the embed code.

Lyrics:

There's antimony, arsenic, aluminum, selenium,And hydrogen and oxygen and nitrogen and rhenium,And nickel, neodymium, neptunium, germanium,And iron, americium, ruthenium, uranium,Europium, zirconium, lutetium, vanadium,And lanthanum and osmium and astatine and radium,And gold and protactinium and indium and gallium, (gasp)And iodine and thorium and thulium and thallium.There's yttrium, ytterbium, actinium, rubidium,And boron, gadolinium, niobium, iridium,And strontium and silicon and silver and samarium,And bismuth, bromine, lithium, beryllium, and barium.There's holmium and helium and hafnium and erbium,And phosphorus and francium and fluorine and terbium,And manganese and mercury, molybdenum, magnesium,Dysprosium and scandium and cerium and cesium.And lead, praseodymium and platinum, plutonium,Palladium, promethium, potassium, polonium,And tantalum, technetium, titanium, tellurium, (gasp)And cadmium and calcium and chromium and curium.There's sulfur, californium and fermium, berkelium,And also mendelevium, einsteinium, nobelium,And argon, krypton, neon, radon, xenon, zinc and rhodium,And chlorine, carbon, cobalt, copper, tungsten, tin and sodium.These are the only ones of which the news has come to Harvard,And there may be many others but they haven't been discovered
