Answer
a. Sublevel 3d has 5 orbitals.
b. The n=1 energy level has 1 sublevel.
c. Sublevel 6s has 1 orbital.
d. The n=3 energy level has 9 orbitals.
Work Step by Step
You can find the answer to this question on page 124, topics 'Sublevels' and 'Orbitals'.
d. the n=3 energy level has 3 sublevels (s with one orbital, p with 3 orbitals and d with five orbitals) which means level 3 has 9 orbitals ( 1+3+5).
figure 4.13 has the number of sublevels and orbitals of the energy levels 1,2,3 and 4.
