Tellurium Ion and Electron Configuration

This video tutorial explains how to write the Lewis structure for Tellurium (Te) by determining its valence electrons using two methods: the periodic table and electron configuration. It also covers how Te forms a Te2- ion by gaining electrons to complete its octet, and the importance of using brackets for ions. The video concludes with a brief overview of the electron configuration method to identify available electrons for bonding.

Why do we put brackets around the Te2- ion in its Lewis structure?

• To indicate it is a molecule

• To differentiate it from other elements

• To show it is an ion

• To highlight its valence electrons

What is the significance of the 4D subshell in Tellurium's electron configuration?

• It is empty and irrelevant

What is the condensed electron configuration notation used for?

• To represent the atomic number

• To simplify the representation of core electrons

• To show all electrons in detail
