♥ Transition Metals
The 38 elements in groups 3 through 12 of the periodic table are called "transition metals". As with all metals, the transition elements are both ductile and malleable, and conduct electricity and heat. The interesting thing about transition metals is that their valence electrons, or the electrons they use to combine with other elements, are present in more than one shell. This is the reason why they often exhibit several common oxidation states. There are three noteworthy elements in the transition metals family. These elements are iron, cobalt, and nickel, and they are the only elements known to produce a magnetic field.
The 38 transition metals are:
Scandium
Titanium
Vanadium
Chromium
Manganese
Iron
Cobalt
Nickel
Copper
Zinc
Yttrium
Zirconium
Niobium
Molybdenum
Technetium
Ruthenium

♥ Periodic Table
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 ("periodic") 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 now ubiquitous within the academic discipline of chemistry, providing an extremely useful framework to classify, systematize and compare all of the many different forms of chemical behavior. The table has found wide application in chemistry, physics, biology, and engineering, especially chemical engineering. The current standard table contains 117 elements as of March 10, 2009 (elements 1-116 and element 118).

♥ The Element Song
Lyrics to the element song:
There's antimony, arsenic, aluminum, selenium,And hydrogen and oxygen and nitrogen and rheniumAnd nickel, neodymium, neptunium, germanium,And iron, americium, ruthenium, uranium,Europium, zirconium, lutetium, vanadiumAnd lanthanum and osmium and astatine and radiumAnd gold, protactinium and indium and gallium (inhale)And iodine and thorium and thulium and thallium.
There's yttrium, ytterbium, actinium, rubidiumAnd boron, gadolinium, niobium, iridiumAnd strontium and silicon and silver and samarium,And bismuth, bromine, lithium, beryllium and barium.
There's holmium and helium and hafnium and erbiumAnd phosphorous and francium and fluorine and terbiumAnd manganese and mercury, molybdinum, magnesium,Dysprosium and scandium and cerium and cesiumAnd lead, praseodymium, and platinum, plutonium,Paladium, promethium, potassium, polonium, andTantalum, technetium, titanium, tellurium, (inhale)And cadmium and calcium and chromium and curium.
There's sulfur, californium and fermium, berkeliumAnd also mendelevium, einsteinium and nobeliumAnd argon, krypton, neon, radon, xenon, zinc and rhodiumAnd 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.
