In 3-5 sentences, describe the matter that is considered baryonic matter, explain why it is in this category, and compare and contrast it with other materials in the universe.

Baryonic matter is built by baryons and leptons

Baryonic matter is the energy that surrounds us, including ourselves

Baryonic matter constitutes only 4% of the density of the universe

Explanation:

The baryons are subatomic particles. The most representative, for forming the nucleus of the atom, are the neutron and the proton; but there are also a large number of baryons, although these are all unstable. The name of baryon is due to the fact that it was believed, when it was discovered, that it had a greater mass than other particles.

In physics, a lepton is a particle with spin 1/2 in the case of neutrinos and + / - 1/2 in the other leptons (a fermion) that does not undergo strong interaction. Leptons are part of a family of elementary particles known as the fermion family, just like quarks.
