← ScienceWhich outcome occurs when californium-252 undergoes alpha decay?
A)Curium-248 and helium nucleus form✓
B)Plutonium-252 becomes more stable
C)Californium captures a stray neutron
D)Americium-248 spontaneously generates neutrons
💡 Explanation
Curium-248 and an alpha particle (helium nucleus) result because alpha decay reduces the atomic number via emission of two protons and two neutrons. Therefore, the product is curium and helium, rather than plutonium, because a different decay process occurs.
