Question

what noble gas should be used to write the shorthand configuration for te?

Explanation:

To write the shorthand electron configuration for an element, we use the noble gas that comes before it in the periodic table. Tellurium (Te) is in period 5. The noble gas in period 4 is Kr (Krypton), but wait, no - actually, let's check the atomic numbers. The atomic number of Te is 52. The atomic number of Kr is 36. The atomic number of Xe (Xenon) is 54. But in the shorthand configuration, we go to the noble gas of the previous period. Te is in period 5. The noble gas of period 4 is Kr. But wait, no - the correct approach is: The electron configuration of Te is \(1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{6}5s^{2}4d^{10}5p^{4}\). The noble gas core for Te is \([Kr]5s^{2}4d^{10}5p^{4}\) because Kr (\(Z = 36\)) has the configuration \(1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{6}\)

Answer:

Kr
