The mass of a proton is about 1.672621777x10-27 kg. The mass of a neutron is about 1.674927351x10-27 kg. The difference is about 2.305574x10-30 kg.
The number of neutrons is the difference between mass number and the number of protons.
Ar-39 has 21 neutrons Ar-40 has 22 neutrons
Mendelevium 256 has 155 neutrons and mendelevium 258 has 157 neutrons.
As they are isotopes, they've different number of neutrons.
Calcium-40: The atomic number of calcium is 20 and the number of neutrons is always the difference between the atomic mass and the atomic number.

- protons are positive and neutrons are neutral- a small difference of mass exist
no of neutrons in protium is 0 but not in deutirium and tritium.as the no of neutrons is difference between atomic mass and atomic number.
The difference between isotopes of the same element have to do with the number of neutrons present in the nucleus of the atom. Isotopes are atoms of an element that contain the same number of protons, but different numbers of neutrons and therefore different mass.
The difference is the amount of neutrons in the atom Oxygen 16 has 8 oxygen 17 has 9 neutrons

It is equal to the difference between atomic number and Atomic Mass number. A+
The number of neutrons is the difference between mass number and the number of protons.
macro is bigger than micro
Two more neutrons
Degrees from online course schools are generally looked at as slightly lower than those from in class schools. However, the difference in between the way they are regarded is not very high.
