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 atomic number?115. This signifies 115 protons within the nucleus
2. What is the element classification?Synthetic Superheavy Element
3. How do scientists make Ununpentium?Scientists create it by bombarding a target of Americium‑243 with a beam of fast Calcium‑48 ions in a particle accelerator. The collision forces the nuclei to merge and form the element for a very short time.
4. How long does Ununpentium last?Ununpentium only lives for a few milliseconds before it breaks apart. Its half‑life is measured in milliseconds.

Superheavy Element: Elements with atomic numbers greater than 104, characterized by extreme instability and synthetic origin.
Nuclear Fusion: The process of combining two atomic nuclei to form a heavier nucleus, often requiring high energy.
Alpha Decay: A type of radioactive decay where an atomic nucleus emits an alpha particle (two protons and two neutrons).
Island of Stability: A theoretical region where certain superheavy isotopes are predicted to have significantly longer half-lives than their neighbors.
