Answer

Explanation:

Step1: Recall atomic - mass formula

Atomic mass ≈ number of protons + number of neutrons. For neutral atoms, the number of protons is equal to the atomic number. The atomic numbers of Sn (tin) = 50, Sb (antimony) = 51, Te (tellurium) = 52, I (iodine) = 53.

Step2: Calculate number of neutrons approximation

For Sn: Neutrons ≈ 118.71 - 50 = 68.71. For Sb: Neutrons ≈ 121.76 - 51 = 70.76. For Te: Neutrons ≈ 127.60 - 52 = 75.60. For I: Neutrons ≈ 126.90 - 53 = 73.90.

Answer:

tellurium (Te)
