He was explore one of the most important things in the history of chemistry.It is the atom.

Born Rutherford on 30 August 1871

Education: university of Zealand 🇳🇿

And university of Cambridge


Scientific career

Atomic physics

Died: 19 October 1937 (66 years)

Note: Rutherford has it element

(Rutherfordium)

Rutherford's model proposed that the negatively charged electrons surround the nucleus of an atom.
