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. Who discovered Roentgenium?GSI Helmholtz Centre for Heavy Ion Research
2. What is the scientific name?Roentgenium
3. What is the element symbol?Rg
4. How do scientists make Roentgenium?They smash bismuth atoms with nickel atoms inside a particle accelerator. This creates only a few atoms of Roentgenium, so it is hard to study.
5. How long does Roentgenium last?The most stable form, Roentgenium‑282, lasts about 130 seconds. Scientists think a different form, Roentgenium‑286, might last up to 10.7 minutes.

Superheavy Element: Elements with atomic numbers greater than 103, typically synthesized and highly radioactive.
Nuclear Fusion: The process where two or more atomic nuclei combine to form one or more different atomic nuclei.
Island of Stability: A theoretical region where certain superheavy isotopes are predicted to have significantly longer half-lives.
Relativistic Effects: Quantum mechanical effects that become significant for heavy elements due to their high atomic numbers and electron speeds.
