Question
**Title:** Understanding Radial Probability Distributions of Orbitals

**Overview:**

This resource provides an illustration of the radial probability distribution for three orbitals, labeled A, B, and C. Each curve indicates the likelihood of finding an electron at various distances from the nucleus, measured in picometers (pm).

**Graph Explanation:**

- **Axes:**
  - **Y-Axis (Probability):** Represents the probability of finding an electron at a specific distance from the nucleus.
  - **X-Axis (Distance from Nucleus):** Measures the distance in picometers.

- **Curves:**
  - **Orbital A (Red Curve):** Peaks around 1500 pm, indicating a higher probability of finding an electron at this distance.
  - **Orbital B (Green Curve):** Peaks around 2500 pm.
  - **Orbital C (Blue Curve):** Peaks around 500 pm, showing multiple wave-like oscillations close to the nucleus.

**Questions:**

1. **What is the most likely distance from the nucleus for an electron in orbital B?**
   - *Note:* Your answer must be within 50 pm of the exact answer to be graded correct.

2. **List the orbitals in order of increasing energy:**

3. **Suppose all three orbitals were inner orbitals of an atom. In which orbital would an electron be most effective at screening the charge of the nucleus from the outer electrons?**

**Instructions:** Use the graph to determine the most likely distance for electron presence, compare energy levels, and assess screening effectiveness based on the provided curves. Select the most appropriate answer from the options.
