Which of the following is the electron configuration for Tellurium (Te)?

To determine the correct electron configuration for Tellurium (Te), which has an atomic number of 52, we need to know how to build the electron configuration according to the Aufbau principle, Hund's rule, and the Pauli exclusion principle.

The correct electron configuration for Tellurium is [Kr] 5s² 4d¹⁰ 5p⁴. This notation indicates that Tellurium has the following distribution of electrons:

1. The noble gas preceding Tellurium in the periodic table is Krypton (Kr), which has an atomic number of 36. The electron configuration for Krypton is used as the starting point for Tellurium's configuration.

2. After Krypton, the next electrons fill the 5s orbital with 2 electrons, indicated by the 5s².

3. Following the 5s orbital, the 4d subshell is filled next with a total of 10 electrons, as represented by 4d¹⁰.

4. Finally, the 5p subshell is filled with 4 electrons, leading to 5p⁴.

When you combine all these parts, you correctly arrive at the full configuration for Tellurium: [Kr]
