Step 1 · Read the article

Open the article and read it at the level above. Then answer the questions below in your own words.

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 group number?18
2. What is the electron configuration?Full valence electron shells (ns²np⁶, except He: 1s²)
3. What makes noble gases so unreactive?Noble gases have full outer electron shells, giving them high ionization energies and almost no electron affinity. This makes them very unlikely to form chemical bonds.
4. How do we get noble gases from the air?Air is cooled and compressed until it liquefies. Then, by slowly warming the liquid, each noble gas boils off at its own temperature and can be collected.

Valence Electron Shell: The outermost electron shell of an atom, which dictates its chemical behavior and bonding.
Monatomic: Consisting of single, unbonded atoms; characteristic of noble gases in their elemental form.
Cryogenic: Relating to very low temperatures, typically below -150 °C.
Relativistic Effects: Quantum mechanical effects that become significant for electrons moving at speeds close to the speed of light in heavy atoms.
