The simplest atom would arguable be hydrogen, containing just one proton and one electron. There are other hydrogen atoms, known as isotopes, all of which contain nuetrons.

Hydrogen 1 is known as protium, or normal hydrogen. H-2 is dueterium with one proton, one nuetron and one electron. H-3 is tritium. Any isotopes above H-3 are highly unstable and exist for fractions of a second.
