D-block
periodic table block; on the middle of the periodic table and includes elements from groups 3 through 12
The D-block is a group of elements on the periodic table. They include the transition metals. The Group 12 elements are normally called post-transition metals because they are different from the transition metals. The Group 12 elements are still in the d-block though. The d-block can hold up to ten (10) electrons at most.
