That’s kind of an abstract question
Hydrogen usually comes in 2 different forms - elemental hydrogen and hydronium ions
An equation with a hydronium ion would be the dissociation of an Acid in water
Ex, HCl —> H+ + Cl-
Hydrogen’s electron is now orbiting around Chlorine, thus making it simply a Neutron and Proton.
In elemental form, hydrogen is diatomic it can only be found by itself if bonded to another H atom
Ex (unbalanced), H2 + O2 —> H2O
Hope this helps
