All isotopes and ions of hydrogen have one proton.
H-1. Hydrogen has only one proton and electron; if this electron is removed a hydrogen ion is formed - effectively a proton.
A lone proton can also be referred to as a hydrogen ion.
A proton is a subatomic particle found in the nucleus of an atom. A hydrogen ion, on the other hand, is a positively charged ion of hydrogen that has lost its electron. So, a hydrogen ion is essentially a proton outside of the nucleus.
A proton.
A hydrogen ion is often referred to as a proton due to its single positive charge.
Hydrogen H+ ion is (i.s.o. 'can be thought of as ...) one proton.
A hydrogen ion, when in reaction, usually donates its core which essentially is a proton that attracts negative charges, which in turn makes the positively charged hydrogen ion an electrophile.
The proton is an elementary particle with the mass 1.00727646677 atomic units of mass and the electrical charge +1. It is a hydrogen ion in which one electron is lost. But since hydrogen only has one electron and one proton, a hydrogen ion is just called a "proton", since only a proton is left.
A proton
The hydrogen ion H+ has no neutrons.
Proton and technocally neutron because Hydrogen's most common isotope doesn't have neutrons, but that small decimal at the end shows a small percentage of isotopes which have neutrons. Electrons are so small you don't take them into account for mass
H+ can be either called a hydrogen ion or a proton.
