- These atoms probably can't be destroyed either
- But there was still more to discover about the atom. This was proven by JJ Thomson, when he discovered electrons in 1897.
- Another physicist named Ernest Rutherford discovered that electrons orbited around a nucleus in the centre of an atom in 1911.
