What year was the electron discovered?

1897

Where were you when the electron was discovered? Well, the discovery took place in 1897, so the answer to that question is probably, “not born.” Yes, it was in that year that J.J. Thomson, an English physicist, proved electrons – subatomic particles with a single unit of negative electricity – were present in the flow of electric current. The discovery took place in Cambridge, England, at the Cavendish laboratory, and Thomson went on to win the Nobel Prize for Physics in 1906. Sources: Encyclopedia.com, Nobelprize.org
