2 cards from this section. Quick, good the night before a test.
What is a nucleus?
Think about what parts of an atom are dense and contain mass.
Define isotopes.
Consider how elements can have variants based on their neutron count.
What is an atomic mass unit?
Remember how we define mass in terms of carbon.
Radioactivity involves the emission of energy and particles from atomic nuclei.
Consider what happens when nuclear structures become unstable.
Calculate the binding energy for carbon-14 if its mass defect is 0.093 u.
Don't forget to convert the mass defect to energy!
Explain how stability in nuclei can be dependent on neutron to proton ratio, and calculate this for a hypothetical nucleus with 8 proton and 12 neutrons.
Remember the ratios of stability as we discussed.
