Which element is 1 proton, 1 electrons? Is it a neutral atom or ion?

An element with 1 proton and 1 electron is hydrogen (H). Since it has an equal number of protons (which are positively charged) and electrons (which are negatively charged), it is a neutral atom. If it were to have either more protons than electrons (resulting in a positive charge) or more electrons than protons (resulting in a negative charge), it would be an ion. But in this case, with 1 proton and 1 electron, hydrogen is indeed a neutral atom.
