The element Lanthanum (La) is a transition metal and the first of the 'Lanthanides'.
The elements in the center section are called transition elements.
In the periodic table. See the related link for an excellent version in Wikipedia. Scroll down to the section 'structure'to see the elements laid out before you. Just hover your mouse pointer over each element for the full name.

A reasonable value for the atomic mass of the missing element can be estimated by finding the average atomic mass of the elements on either side of the missing element in the periodic table. This estimation assumes a gradual increase in atomic mass across the periods in the table.
Brass is a compound (or to be technically correct, an alloy) made from the elements zinc and copper. Both of these elements can be found in the transition metals section of the periodic table.
the main blocks of element Cr in is d-block orbital in the periodic table because element Cr is a transition element.
The Lanthanides are a Period of Elements in the sixth period. They all metals. They all have variable oxidation states, but oxudation state '3' is the most stable. They lie in the Periodic Table between Group (II) (Alkaline Earth metals) and the Transition Metals.
The elements in the center section are called transition elements.
Most of the lanthanides are silvery-gray metals. Check the Related Links section for pictures of all of them.
Alkaline Earth Metals.....
The transition elements are found all in the middle, but don't include Lanthanum and Actinium together with it. Because those two are all from the Rare Earth Elements section.Here is the link with a picture of it. Should be able to give you a clear open of mind about periodic table.http://www.modelscience.com/PeriodicTable.html
The d-sub level section of elements on the periodic table is often referred to as the "transition metals." These elements are located in groups 3 to 12 and have partially filled d orbitals in their electron configurations.
The central section of the periodic table is called the transition metals. These elements are located in groups 3-12 and are known for their ability to form colored compounds and show variable oxidation states. They often exhibit metallic properties such as high electrical conductivity and malleability.
A period on the periodic table is a row.This is the horizontal section of the periodic table.
