Atomic mass: The standard atomic weight of an element is the average mass of the element written in atomic mass units (amu). Even though each atom has roughly a whole number of atomic mass units, ...

The atomic mass is usually measured in atomic mass units (amu), where 1 amu is defined as one-twelfth of the mass of a carbon-12 atom. >Mass of Neutron = 1.008 amu >Mass of Proton = 1.00727647 amu ...

For example, you may have a card that says that the atom you are looking for has 5 neutrons. You would look at the periodic table to find an atom that you could add 5 to its number of protons that ...
