IB Physics Atomic Mass
/A tutorial sheet on atomic mass follows.
- Define the term atomic mass.
- What is the atomic mass of the C-12 atom?
- The atomic mass of carbon is 12.011 u. Why is this not exactly 12 u?
- Is 1 u the mass of one proton?
- Is the mass of a nucleus equal to A u where A is the mass number of the nucleus?
- Give two reasons why the mass in u of a nucleus is not equal to the mass number of the nucleus. (protons and neutrons have a slightly different mass, the nuclear binding energy varies between nuclei; for two nuclei having the same mass number the one with greater binding energy will have a smaller mass).
