Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the year of introduction?1963
2. What is the originating research location?University of Rome, Italy
3. What is the decay technique in chemistry?The decay technique is a special method where scientists use radioactive atoms to create very short‑lived chemical species that are otherwise hard to make.
4. How does radioactive decay help make new chemical species?When a radioactive atom such as tritium turns into another atom, it releases energy that can break bonds and form new, highly reactive molecules like radicals or carbocations right inside the sample.

Transient Chemical Species: Molecules or ions that exist for very short durations, often milliseconds or less.
Radiolabeled Molecules: Compounds containing radioactive isotopes used as tracers or to initiate decay processes.
Astrochemistry: The study of the abundance and reactions of chemical compounds in the universe.
