Explanation:

Step1: Recall the relationship formula

Atomic mass = number of protons + number of neutrons. Also, atomic number = number of protons.

Step2: Identify given values

Given atomic mass = 36 and atomic number = 25. Since atomic number = number of protons, number of protons = 25.

Step3: Calculate number of neutrons

Number of neutrons = Atomic mass - number of protons. Substitute values: 36 - 25 = 11.

Answer:
