Answer:
The element has 33 neutrons
Explanation:
1. Find the mass number:
Mass number = number of protons + number of neutrons
Mass number = 71
2. Find the atomic number:
Atomic number = number of protons
Atomic number = 38
3. Find the number of neutrons:
Number of neutrons = Mass number - Atomic number
Number of neutrons = 71 - 38
Number of neutrons = 33
