There are eight third period transition elements on the periodic table.
Transition elements reside in the Transition Metals section of the Periodic Table. Groups in this section always contain four elements. This section has most of the known elements in and it includes the Lanthanides and Actinides.

There are two elements, carbon and hydrogen.
The current periodic table contains 118 elements, as of April 2010, but many more may still be discovered.
The 3rd family on the periodic table is the Boron family, also known as Group 13. It includes elements such as Boron, Aluminum, Gallium, Indium, and Thallium. These elements have three valence electrons.

Metal.
Transition elements are a group of elements in the periodic table located in the d-block. They are characterized by their partially filled d orbitals, which give them unique chemical and physical properties. Transition elements often exhibit multiple oxidation states and form colorful compounds.
There are 2 elements in the first period, 8, 8 elements in 2nd and 3rd periods respectively,
The 3rd shell can contain 18 electrons. The elements that have a 3rd shell as the outer shell are the the elements in period 3, where the 3s and 3p orbitals are filled to a maximum of 8 electrons. The 3d orbitals are filled in the 4th period in the transition elements.
