Transition Metals

Change of atomic radius:

The atomic radios of the elements increases by one electron shell in every element bellow and every element has the same number of electrons in the outer electron shell.

Location on the period table:

Transition Metals in the mid area of the period table because the placement depends on the number of electrons on the outer shell.


Transition metals do not react as much as Alkali Metals, because the elements have a protective oxide layer that demands them to remove at least 2 or 3 electrons, but Alkali Metals only need to remove 1.


Most transition metals are used for building materials, tools, vehicles, fighter aircraft, artificial hip joints, pipes in nuclear power stations and metal objects. The uncommon transition metals such as Copernicium, Darmstadtium  and Hassium  are only used for scientific research.Like all metals the transition elements are both ductile and malleable, and conduct electricity and heat. Iron, cobalt and nickel are the only elements that  are known to produce a magnetic field.

Melting and Boiling point:

The melting and boiling points increase as you go down the list except for the last 2 groups, for the last 2 groups the melting and boiling points decrease as you go down the list. But in the last few elements it starts increasing again. The density of transition metals is high, because metals are hard  elements .Which takes a higher temperature and longer to melt and boil.

Abundance on Earth:

Iron, copper and silver are the most abundant elements on Earth,they are found in nature and the uncommon transition metals are not found in nature. The  most important and useful transition elements are rare,for example  tungsten, platinum, gold, and silver. A few transition metals are manmade, for example technitium (Tc).
