What is the term for the element produced after decay?

• A. Product
• B. Parent material
• C. Isotope
• D. Daughter material

Answer: (D)

In radioactive decay, the nucleus that results from the decay is called the daughter. The original nucleus is the parent, so the lineage is parent → daughter. This naming highlights the progression from what existed before to what is produced after the decay event. The daughter can be a different element depending on the type of decay (for example, alpha decay changes the element, while beta decay changes the element as well). Isotopes are variants of the same element with different neutron numbers, which isn’t what’s produced by decay. The term “parent material” refers to what decayed, not what remains after, and while “product” is technically accurate, the standard, precise term used in decay chains is “daughter material.”
