Naked proton:
H+. When an electron (e-) is removed
from an atom of the most
common
hydrogen isotope (1H), only a naked proton
(a proton
with nothing else) remains. The symbol H+ implies a
naked proton,
although it is often used to mean aqueous
H+, which case better symbols are H+(aq.), H3O+
(the hydronium ion), or H+(H2O)n.
In general H+ is an accepted notation in introductory
or general chemistry but not in organic
chemistry. In organic
chemistry "H+" can be used to indicate an
unspecified acid
(a proton source). A naked proton
is a subatomic particle, which exists in places like interstellar
space and physics textbooks, but not in solution chemistry.
