boson

A boson is a nuclei with an even mass number. Bosons are subatomic particles.

An atom isn’t the smallest thing in the world: there are also subatomic particles, such as bosons. Bosons get their name from Indian physicist S. N. Bose, who first described their behavior. If you want to understand bosons thoroughly, you'd better take a class in in particle physics. In a nutshell, a boson has a symmetric wave-function, therefore obeying Bose-Einstein statistics but not the Pauli exclusion principle. Physicists study bosons to understand how the universe works at the tiniest level.
