Answer to Problem 128A
The element in groups 3 to group 12 is known as transition elements. They have completely filled or partially filled d-orbitals.
Explanation of Solution
Transition elements are known as d- block elements and they have partially filled d sub-shell. They are found in the periodic table from group 3-group 12. The transition elements are classified as transition metals and inner transition metals. The inner transition metals are known as the lanthanide series and the actinide series.
Transition elements (d-block) usually have a filled s-orbitals of energy level n and filled or partially filled d-orbitals of energy level
