As a rule of thumb, any atom with an even number of electrons + protons + neutrons is a boson. So, e.g., ordinary sodium atoms are bosons, and they can merge to become Bose-Einstein condensates.

Are atoms bosons or fermions?

It turns out that all integer-spin particles (such as photons, mesons, and neutral atoms with an even number of neutrons) are bosons, and all half-integer spin particles (such as electrons, protons, neutrons, and all neutral atoms with an odd number of neutrons) are fermions.

What particles are bosons?

Bosons are those particles which have an integer spin (0, 1, 2...). All the force carrier particles are bosons, as are those composite particles with an even number of fermion particles (like mesons).
