Which of the following is true about mass-energy changes in nuclear decay?
An isotope of mass number has a binding energy per nucleon of . What is the total energy released if of this isotope is formed from separated nucleons?
…
A nuclide undergoes decay. Which of the following changes occurs in the nucleus?
A graph of binding energy per nucleon against nucleon number shows it is approximately constant for nuclides with more than nucleons. What can be determined from this finding?
A radioactive sample initially has of isotope X. After hours, only remains. What is the half-life of the isotope?
The mass of the products is always greater than the reactants
The mass of the products is less, and the difference is released as energy
There is no mass difference before and after the reaction
The mass increase corresponds to energy absorption
A neutron is converted into a proton
A proton is converted into a neutron
A neutron is ejected
An alpha particle is emitted
That the strong nuclear force has a very short range
That protons and neutrons are composed of quarks
That nuclides with more than nucleons are unstable
