To calculate the mass excess of hydrogen, we can follow these steps: Step 1: Understand the Concept of Mass ExcessMass excess is defined as the difference between the actual mass of a nucleus and its mass number
the mass of a hydrogen atom 1/1H is equal to 1/12 of the mass of a carbon-12 atomso its relative isotopic mass is 1.A magnesium atom 24/12Mg is twice as heavy as a carbon-12 atom,so its relative isotopic mass is 24再给另一个例子...
