|
|
|
No. of neutrons

Explanation:
Detailed explanation-1: -Together, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.
Detailed explanation-2: -Charge and Mass of Neutrons The electric charge that is associated with a neutron is 0. Therefore, neutrons are neutrally charged subatomic particles. The mass of a neutron is roughly equal to 1.008 atomic mass units.
