No actually. it all comes down to particle physics and that is all rather uncertain. No-one has ever seen an electron, just observed their effects and postulated they exist. Science is unsure if they are a wave or a particle or both. The best scientists believe electrons exist, but there was a time they believed the world was flat (we'll not really - do you watch QI?) and though leeches were the treatment for many ailments (although they do use them in cases of amputations and grafts now).
Secretly I would enjoy it if electrons were disproved, but that's my sense of humour.
