Here's a breakdown:
* Proton: A positively charged particle found in the nucleus of an atom.
* Electron: A negatively charged particle that orbits the nucleus of an atom.
This simple structure makes hydrogen the lightest and most abundant element in the universe.
It's important to note that there are isotopes of hydrogen, meaning variations with different numbers of neutrons. The most common isotope is protium, which only has a proton and an electron. However, there are also deuterium (with one proton, one neutron, and one electron) and tritium (with one proton, two neutrons, and one electron).
