Problem

Nucleus

P

has a binding energy per nucleon of

8.8\,\text{MeV}

, while nucleus

Q

has

7.6\,\text{MeV}

. Which statement about their relative stability is correct? (a)

P

is less stable because it has the higher total binding energy. (b)

Q

requires more energy to separate its nucleons. (c)

P

is more stable because each nucleon is more tightly bound. (d)

Q

is more stable because it contains fewer nucleons.
