History of The Transition Metals

The creator of the Periodic table was a Russian chemist and inventor named Dmitiri Mendeleev. He published his first periodic table in 1869. (shown above)


The chemistry of the Transition Metals is determined by the extent to which the D electron levels are filled. Chemical similarities can be easily seen horizontally across the d-block of the Periodic Table. The chemistry is far from simple, however, there are many exceptions to the specific filing of the electron shells. As recently stated, the chemical properties in the Periodic Table are grouped in two ways: vertically, or by group, Horizontally, by row or by period, for consistent periodic changes. For example, the Transitions metals in group 11 have similar characteristics of electrical conducting strength.

Uses/Products of the Transition Metals

The transition metals include most of the recognized metals, such as iron, copper, nickel, silver, and gold. Most of the transition metals are hard and shiny. Gold, copper, and some other transition metals have different colors. All of the transition metals are good conductors of electricity. The transition metals are mostly stable, reacting slowly or not at all with air and water. Ancient gold coins and jewelry are as beautiful and detailed today as they were thousands of years ago. Even when iron reacts with air and water, forming rust, it sometimes takes many years to react fully, not at all like the violent reactions of the alkali metals. Would you believe that you use transition metals inside your body? In fact, you would not survive very long without one of the transition metals--iron. Iron is an important part of a large molecule called hemoglobin, which carries oxygen in your bloodstream. Hemoglobin gives blood its bright red color.

Environmental and Safety Concerns

Mercury is highly toxic.The pure metal is absorbed easily by inhalation, ingestion or through the skin.


Long-term exposure to copper can cause nose irritation, mouth and eyes irritation and it causes headaches, stomach aches, dizziness, vomiting and diarrhea. Intentionally large exposure of copper may cause liver and kidney damage and even death.



Where are the Transition Metals located?

The elements in Groups 3 through 12 are called the transition metals. They are called "transition metals" because they are metal elements that serve as a transition, between the two sides of the periodic table. Transition metals are the only elements that can produce a magnetic field. The elements known as Transition Metals are: Scandium Titanium Vanadium Chromium Manganese Iron Cobalt Nickel Copper Zinc Yttrium Zirconium Niobium Molybdenum Technetium Ruthenium Rhodium Palladium Silver Cadmium Lanthanum Hafnium Tantalum Tungsten Rhenium Osmium Iridium Platinum Gold. There is only one liquid transition metal at room temperature. It is Mercury (Hg). All the others elements in the transition metals are solid.

Iron, Gold and Silver's discovery location is unknown because they were all discovered BC and they are known to the ancients.
