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 first transuranic element?Neptunium (atomic number 93), synthesized in 1940
2. What is the primary synthesis technique?Heavy-ion fusion reactions in particle accelerators
3. What are synthetic elements?Synthetic elements are new building blocks made by scientists in labs. They have atomic numbers higher than uranium (92) and are not found in large amounts on Earth. They are created by smashing atoms together in powerful machines.
4. How do scientists create synthetic elements?Scientists use nuclear reactors or particle accelerators to hit a heavy target with fast ions. The collision can fuse the atoms together to form a new element, like how Oganesson was made by hitting Californium with Calcium ions.

Transuranic Element: An element with an atomic number greater than 92 (Uranium).
Superheavy Element: Elements with very high atomic numbers, typically beyond 103, often synthesized artificially.
Island of Stability: A theoretical region of the chart of nuclides where superheavy isotopes are predicted to have longer half-lives.
