#### Consider the Isoelectronic Ions F⁻ and Na⁺
**Part B: Calculation of Effective Nuclear Charge (Z_eff)**
Using the equation:
\[ Z_{\text{eff}} = Z - S \]
- **Z** is the atomic number.
- **S** is the screening constant.
**Assumptions:**
- Core electrons contribute 1.00 to the screening constant.
- Valence electrons contribute 0.00 to the screening constant.
**Objective:**
Calculate \( Z_{\text{eff}} \) for the 2p electrons in both ions F⁻ and Na⁺.
**Instructions:**
- Express your answers as integers.
- Enter your answers numerically, separated by a comma.
**Input Box:**
\[ Z_{\text{eff \ F}^{-}, \ \text{Z}_{\text{eff \ Na}^{+}} = \ \ \_\_\_ \]
