Answer:
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
Step-by-step 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.
