Who provided the evidence that atom contains subatomic particle?
It was J. J. Thomson (Joseph John Thomson)
When did JJ Thomson discover the electron?
J.J. Thomson discovered the electron in 1897 while conducting experiments on cathode rays. He observed that these rays could be deflected by electric and magnetic fields, leading him to propose the existence of a negatively charged particle within the atom, which he named the electron.
