Answer

Explanation:

Step1: Record atomic numbers

Atomic number of Sn is 50, Sb is 51, Te is 52, I is 53.

Step2: Recall formula for neutrons

Number of neutrons = Atomic - mass - Atomic number.

Step3: Calculate neutrons for Sn

For Sn, atomic - mass is 118.71. Neutrons = 118.71−50 = 68.71.

Step4: Calculate neutrons for Sb

For Sb, atomic - mass is 121.76. Neutrons = 121.76−51 = 70.76.

Step5: Calculate neutrons for Te

For Te, atomic - mass is 127.60. Neutrons = 127.60−52 = 75.60.

Step6: Calculate neutrons for I

For I, atomic - mass is 126.90. Neutrons = 126.90−53 = 73.90.

Answer:

tellurium (Te)
