Titanium atoms have electrons in 1s, 2s, 2p, 3s, 3p, 4s, and 3d orbitals. Which of the following has the orbitals listed in the order of decreasing screening ability?

Question

Quizplus · Accepted Answer

Screening ability decreases as you move from lower energy levels to higher ones and from s and p orbitals to d orbitals. Thus, the correct order is 2s, 2p, 3s, 3d, reflecting the decrease in screening ability with increasing energy level and the lower screening effect of d orbitals compared to s and p orbitals.
