Question

what is the shorthand or noble gas electron configuration for tellurium, te? kr 5s² 4d¹⁰ 5p⁴ xe 5s² 4d¹⁰ 5p⁴ ar 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ 5p⁴ kr 5s² 5p⁴

Explanation:

Tellurium (Te) has an atomic number of 52. The noble - gas electron configuration uses the nearest previous noble gas to represent the core electrons. Krypton (Kr) has an atomic number of 36. After [Kr], the remaining electrons fill the 5s, 4d, and 5p orbitals. The electron configuration of Te is [Kr] 5s²4d¹⁰5p⁴ as the 5s orbital fills first (2 electrons), then the 4d orbital (10 electrons), and finally the 5p orbital (4 electrons to reach a total of 52 electrons for Te).

Answer:

[Kr] 5s²4d¹⁰5p⁴
