Proton donors

[sarathornburgh1b]

When the course reader refers to an acid/base as a proton donor/receiver what does that mean? Would this affect an element's atomic number?

[Elan Karlin Dis3H]

When the course reader refers to an acid/base that act as a proton acceptor/donor (acids are donors, bases are acceptors), they are referring to molecule that has a Hydrogen which will separate from the molecule (acid) and bond to another element/molecule (base). When they refer the "proton" they are talking about that hydrogen. Only molecules with a hydrogen can donate a hydrogen. It is a molecule, not an element, that loses this hydrogen therefore the atomic number is unaffected.
