ELEMENT PARTITIONIN ... The sum of the number of protons and neutrons in an element is known as the 'atomic mass number' of the element, and an 'atomic mass unit' is taken to be 1/12th the mass of an atom of Carbon-12. An 'amu' is therefore effectively the mass of a proton+electron or a neutron, and weighs 1.66 x 10^
