Answer:

#"A proton..............."#

Explanation:

Note that the assignment of charge is entirely arbitrary, and a bit unfortunate for #"quantum chemists"# (but not so for #"nucular physicists,"# who don't have to be so careful in multi-proton as compared to multi-electron calculations.) The point is that charged, massive nuclear particles, #"protons"#, have an equal but opposite electronic charge to charged, extranuclear particles of negligible mass, #"electrons"#.

See here for a practical example of assignment of charge on an ion.
