Transition elements are called transition elements because the electrons in these elements are not in process of filling valence(outermost ) shell instead they are, in case of d-block elements, in process of filling penultimate shell. and in case of f- block elements, electrons are in process of filling next to the penultimate shell.

∙ 11y agoThe transition elements have this name because they represent a transition range in which the lowest total electron energy is achieved by filling the f orbitals of the electron shell below the valence shell rather than filling the rest of the valence shell. After all the noted f orbitals have been filled, the transition is over and addition electrons return to filling the valence shell.

∙ 8y agoThe term "transition metals" is for elements which changes the number of electrons in an inner level of electrons (and thus have a transition) from 8 to 18 or from 18 to 32; I consider this term obsolete and confusing.
Currently the term d-block of the Periodic Table is used.

The elements that are characterized by the presence of an incomplete d sublevel are called?
Those elements are called transition elements
Are Lanthanide and actinide elements are transition metals?
Yes, lanthanide and Actinides are transition elements and they are specifically called inner transition elements.
Why are f-block elements called inner-transition elements?
inner transition elements are those who have their last 3 shells incompletely filled. The f block elements have their last 3 shells incompletly filled . That is why they are also called as inner transition elements. what different between inner transition and outer transition elements
What are the elements in the middle of the periodic called?
transition elements
What are elements in groups 3-12 known as?
Transition Metals! ^-^ http://chemistry.about.com/library/blperiodictable.htm
What are the elements in groups 3 through 12 called on the periodic table of elements?
generally groups 3-12 are called the transition metals.
Why d and f block aliments called transition elements?
Transition elements may be defined as those elements which have partialy filled d and f subshells in atomic state so d and f block elements called transition elements.
Why lanthenides are called inner transition elements?
Lanthanide: The first series of inner transitionelements which goes from cerium to lutetium.
WHAT ARE TRANSITION'S?
Elements with incomplete valance shell as well as incomplete penultimate shell are called transition elements.
What are the elements in group 3 to 12 on the periodic table called?
The 38 elements in group 3 through 12 of the periodic table are called Transition Metals.It consist of elements from atomic number 21 to 112. These are also called d block elements.
What are the elements in Groups 3-12 called?
These chemical elements are called transition metals.
Elements in groups 3 through 12 of the periodic table are called?
These elements are known as transition metals or d-block elements
