**Title: Writing the Condensed Electron Configuration for Mn⁴⁺**

**Objective:** Learn how to write the condensed (noble-gas) electron configuration for the Mn⁴⁺ ion.

**Instructions:**

1. **Understand the Concept**
   - The condensed electron configuration uses the noble gas preceding the element on the periodic table as a shorthand.

2. **Identify Nobel Gas Core**
   - For manganese (Mn), the nearest preceding noble gas is Argon (Ar).

3. **Electron Configuration for Mn⁴⁺**
   - Manganese normally has the electron configuration: [Ar] 4s² 3d⁵.
   - For Mn⁴⁺, remove four electrons. These come from the outermost s and d orbitals: 4s² and two from 3d⁵.

4. **Resulting Configuration**
   - The condensed electron configuration for Mn⁴⁺ is: [Ar] 3d³.

**Additional Tips:**

- **Handle Superscripts**
  - When writing multi-digit superscripts or coefficients, list each number in succession.
  
- **Reference Diagram**
  - The diagram helps choose noble gases ([He] to [Rn]) and visualize electron subshells (s, p, d, f) with coefficient numbers (1-6) for writing configurations accurately.

Practice writing out configurations with different ions to reinforce understanding.
