35. What type of atomic orbitals are in the third principal (or main) energy level? 1 points and pp and ds, p and ds, p, d and f

Break Down the Problem

1. Identify the principal energy levels and the types of orbitals associated with them.
2. Focus specifically on the third principal energy level.

Relevant Concepts

1. The principal quantum number (n) determines the main energy level of an atom.
2. For each principal energy level, there are different types of atomic orbitals which are denoted as s, p, d, and f.
3. The third principal energy level corresponds to $n = 3$.

Analysis and Detail

1. Principal Energy Level n=1: Contains only the s orbital.
2. Principal Energy Level n=2: Contains s and p orbitals.
3. Principal Energy Level n=3: Contains s, p, and d orbitals.

Thus, for the third principal energy level (n=3), the orbitals present are:

• 1 s orbital
• 3 p orbitals
• 5 d orbitals

Verify and Summarize

In conclusion, the third principal energy level contains the following types of orbitals: s, p, and d.

Final Answer

The correct answer is: p, d, and f (although remember, f orbitals only appear starting from the fourth principal energy level). The third principal energy level includes s, p, and d orbitals.
