Niels Bohr

Niels Bohr was a Danish physicist who lived between 1885-1962. He investigated atomic structure, modifying Rutherford's old model of an atom. Bohr also claimed that an atom's chemical properties are determined only by the electrons with the largest orbits.

After helping build the first nuclear bomb, Bohr spent the later years of his life promoting peaceful uses of atomic energy.
