No, it is not possible for an atom to have one electron, one proton, and no neutron. The number of protons in an atom determines its atomic number, which corresponds to a specific element on the periodic table. Each element has a unique number of protons in its nucleus. However, all known elements with atomic numbers greater than one have at least one neutron in addition to the proton(s) in their nuclei.
An atom with one proton and no neutron would correspond to hydrogen-1, which is the most basic and lightest element. Hydrogen-1 does exist in nature, but it still contains one electron to balance the positive charge of the proton. The neutron is necessary for the stability of most elements and assists in controlling the forces within the atomic nucleus.
