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 particle classification?Mesons are composite subatomic particles classified as bosons
2. What is the constituent particles?They are composed of one quark and one antiquark
3. How do mesons help keep atoms stable?Mesons, especially pions, are exchanged between protons and neutrons and give the strong nuclear force that overcomes the repulsion between positively charged protons, keeping the nucleus together.
4. What are pions?Pions are the lightest mesons made from up and down quarks and antiquarks. They are important for nuclear interactions and were first found in 1947.

Standard Model: The theory describing fundamental particles and their interactions, excluding gravity.
Boson: A type of particle with integer spin, which includes force carriers like photons and mesons.
Quantum Chromodynamics (QCD): The theory that describes the strong force binding quarks and gluons together.
Nucleon: A collective term for protons and neutrons, the particles found in the atomic nucleus.
