select the correct answer. the filling of which orbital is represented by the transition metals in period 4? a. 3d b. 3s c. 2s d. 2p

Answer

Brief Explanations:

In the periodic table, the transition - metals in period 4 represent the filling of the 3d orbital. The electron - filling order follows the Aufbau principle. After filling the 4s orbital (which is filled before 3d for period 4 elements), the electrons start to fill the 3d orbitals for transition metals in period 4.

Answer:

A. 3d
