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 isotopic characteristic?Produces proton-rich, neutron-deficient isotopes (p-nuclei) heavier than iron
2. Where does the P-process happen?It mainly occurs in Type Ia supernovae, but scientists also think it can happen in neutron star mergers and some core‑collapse supernovae.
3. Why are p-nuclei rare in the solar system?They need extreme conditions, like the very hot and dense environments of supernova explosions, which are uncommon.

P-process: A nucleosynthetic pathway responsible for creating rare, proton-rich heavy elements in explosive stellar environments.
p-nuclei: The stable, proton-rich isotopes of elements heavier than iron that are not produced by the s- or r-processes.
Photodisintegration: The process where a nucleus absorbs a high-energy photon, leading to the ejection of a nucleon or fragment.
