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 electron configuration?Stable electron shells, particularly filled d-orbitals, lead to low reactivity
2. What is the catalytic applications?Essential in automotive catalytic converters and industrial chemical processes
3. What makes noble metals like gold and platinum so shiny and tough?Noble metals have very stable outer electron shells. This makes them resist oxidation and corrosion, so they stay shiny and tough.
4. Why do noble metals not rust like iron?Because they have high ionization energies and filled d-orbitals, noble metals don't easily lose electrons. That means they don't form rust like iron does.

Oxidation: A chemical reaction where a substance loses electrons, often resulting in degradation.
Ionization Energy: The minimum energy required to remove an electron from an atom or molecule.
Catalytic Converter: A device in vehicles that uses catalysts to convert toxic gases into less harmful ones.
