In all ways besides electric charge.


The only respect in which positrons and electrons differ (under the Standard Model of particle physics ) is that the positron has the opposite electric charge of an electron.

See for details.

As an example, two properties that are equal to both electrons and positrons are mass (about #0.51 MeV#) and spin (#1/2#).
