Answer

Explanation:

Step1: Recall the formula for neutrons

The formula for the number of neutrons (n) is (n = A - Z), where (A) is the atomic mass and (Z) is the atomic number.

Step2: Identify (A) and (Z)

From the periodic - table entry, the atomic number (Z = 76) (the number at the top of the element box) and the atomic mass (A\approx190) (rounded (190.23) to the nearest whole number).

Step3: Calculate the number of neutrons

Substitute (A = 190) and (Z = 76) into the formula (n=A - Z). So (n=190 - 76=114).

Answer:

114
