Which of the following statement(s) is(are) true?

a. A radioactive nuclide that decays from 2.00 × 1021 atoms to 5.0 × 1020 atoms in 16 minutes has a half-life of 8.0 minutes.

b. Nuclides with large Z values are observed to be α-particle producers.

c. As Z increases, nuclides need a greater proton-to-neutron ratio for stability.

d. Those “light” nuclides that have twice as many neutrons as protons are expected to be stable.
