Answer
When boron-10 is struck by neutrons, it produces lithium-7 and an alpha particle.
Explanation
## Step 1: First, we need to understand the given transmutation reaction. Transmutation is the process of changing one element into another, often occurring in radioactive decay processes. The given reaction is:
In this reaction, Boron-10 (B) with atomic number 5 and mass number 10 is struck by a neutron (n) with atomic number 0 and mass number 1, resulting in Lithium-7 (L) with atomic number 3 and mass number 7 and an alpha particle (He) with atomic number 2 and mass number 4.## Step 2:Next, we need to match this understanding with the given statements. The statement that correctly describes this reaction is: "When boron-10 is struck by neutrons, it produces lithium-7 and an alpha particle". This is because in the reaction, boron-10 is indeed struck by a neutron, and the products are lithium-7 and an alpha particle.
