### Short Notation for Electron Configurations

For educational purposes, let’s explore how to use short notation to write the electron configurations for certain elements and ions. The short notation method uses noble gas notation to simplify the representation of electron configurations.

**Question:**

4. Use short notation to write the electron configuration of:

**A) Se**

_________________________________

**B) Te²⁻**

_________________________________

When using short notation for electron configurations:

1. **Identify the nearest preceding noble gas:** This noble gas's configuration will be written in brackets.
2. **Add the remaining electron configuration:** After the noble gas symbol, write the configuration for the remaining electrons to reach the desired element or ion. 

### Example

For Selenium (Se):

1. Locate the nearest preceding noble gas to Selenium (34 electrons), which is Argon (Ar, 18 electrons).
2. Selenium’s configuration: \[ Ar \] 4s² 3d¹⁰ 4p⁴

For Tellurium ion (Te²⁻):

1. Locate the nearest preceding noble gas to Tellurium (52 electrons + 2 extra electrons for the 2- ion), which is Krypton (Kr, 36 electrons).
2. Tellurium’s configuration: \[ Kr \] 5s² 4d¹⁰ 5p⁶
