Boron-10 can absorb neutrons and is therefore used in control rods for nuclear reactors. After B-10 absorbs a neutron, it emits an α particle. Which isotope is produced as a result of neutron absorption followed by α emission?

Question

Quizplus · Accepted Answer

When Boron-10 (B-10) absorbs a neutron, it becomes Boron-11 (B-11). Following the emission of an alpha particle (which consists of 2 protons and 2 neutrons), the resulting isotope loses 2 protons and 2 neutrons. This process transforms it into Lithium-7 (Li-7), as Lithium has 3 protons and the isotope has 4 neutrons (3+4=7).
