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: -Protons have a positive electrical charge of one (+1) and a mass of 1 atomic mass unit (amu), which is about 1.67×10−27 kilograms.
Detailed explanation-3: -Statement 1: Number of neutrons is always greater than or equal to the number of protons in any given atom except hydrogen.
Detailed explanation-4: -Charge and Mass of Neutrons The mass of a neutron is roughly equal to 1.008 atomic mass units. When converted into kilograms, the mass of the neutron can be approximated to 1.674*10-27 kg.
