. Which of the following variables identifies the sublevel that has three orbitals?1 pointdnfsp

To solve the problem, we need to identify the sublevel that contains three orbitals among the given options: d, n, f, and p.

Break Down the Problem

1. Identify the number of orbitals for each sublevel:
   • d sublevel
   • n sublevel
   • f sublevel
   • p sublevel

Relevant Concepts

2. Each sublevel corresponds to a specific number of orbitals:
   • s sublevel: 1 orbital
   • p sublevel: 3 orbitals
   • d sublevel: 5 orbitals
   • f sublevel: 7 orbitals

Analysis and Detail

3. Among the listed sublevels:
   • s has 1 orbital
   • p has 3 orbitals
   • d has 5 orbitals
   • f has 7 orbitals

Thus, it is clear that the p sublevel has exactly three orbitals.

Verify and Summarize

4. Verification:
   • By analyzing the number of orbitals, we confirm that the p sublevel corresponds to three distinct orbitals.

Final Answer

The variable that identifies the sublevel with three orbitals is p.
