Question

what noble gas should be used to write the shorthand configuration for te? sb kr xe ar

Explanation:

Step1: Determine the noble gas before Te

Tellurium (Te) has an atomic number of 52.

Step2: Check noble gas positions

Krypton (Kr) has an atomic number of 36. Xenon (Xe) has an atomic number of 54. Argon (Ar) has an atomic number of 18. Sb is not a noble gas.

Step3: Select the correct noble gas

Since Kr (atomic number 36) is the noble gas with an atomic number less than that of Te (52) and closest to it among the options, it is used for the shorthand configuration of Te.

Answer:

Kr
