A hydrogen ion (H+) has only one subatomic particle, a(n) ______.Multiple choice question.electronprotonorbitalneutron

1. Question Analysis

The question asks about the subatomic particle present in a hydrogen ion (H+).

2. Relevant Concepts

• A hydrogen ion (H+) is formed when a hydrogen atom loses its single electron.
• Thus, an H+ ion has no electrons, neutrons, or protons.

3. Options Evaluation

1. Electron: Not applicable since H+ has lost its only electron.
2. Proton: A hydrogen ion has one proton, which is the nucleus of the hydrogen atom.
3. Orbital: This term refers to the region around a nucleus where electrons are likely to be found; it is not a subatomic particle itself.
4. Neutron: Hydrogen does not have neutrons, and H+ specifically has none.

4. Correct Answer

The only subatomic particle present in a hydrogen ion (H+) is a proton.

Final Answer

A hydrogen ion (H+) has only one subatomic particle, a proton.
