atomic mass unit = 1 amu = 1.67× 10^-27 Kg
unified mass = any compound real mass
for example potassium real mass is 39.9
mass number = number of proton + number of nutrons
mass number always integer .
unified mass = any compound real mass
for example potassium real mass is 39.9
mass number = number of proton + number of nutrons
mass number always integer .

Answer:
An isotope is one of two or more species of atoms with different atomic mass numbers (total number of protons + total number of neutrons) of the same chemical element. ... Atomic weight is measured in units of atomic mass (usually abbreviated to AMU), also known as Daltons.
