Answer:
Hydrogen sometimes is missing an electron and sometimes it has an extra electron.
Explanation:
Hydrogen, in its neutral form, does not have a neutron. There is only one electron and one proton.
Hydrogen can form a diatomic compound H₂ (where each hydrogen atom shares an electron) or it can also be in the form of an ion such as H⁺.
So hydrogen sometimes is missing an electron and sometimes it has an extra electron.
