Answer:

A transition element is an element whose d-block is never fully filled in its atomic state as well as in its ionic state .

Explanation:

  • Elements of Group 3-11 are all transition elements.

Answer:

The elements in the center of the periodic table

Explanation:

They are the elements towards the middle of the periodic table.

They are separated from the rest of the elements because their valence electrons are in both the #"4s"# and #"3d"# subshells.

Transition elements are more strictly defined as elements whose atoms have an incomplete #"d"# sub-shell.

This definition excludes elements in Group 12, as they have full #"d"^10# configurations.

Thus, #"Zn, Cd, Hg"#, and probably #"Cn"# are not transition elements even though they are in the #"d"#-block.
