Niels Bohr
Bohr discovered atomic orbitals. He proposed that electrons
travelling around the nucleus could only occupy orbits
that had fixed energy values, being multiples of n, where n
represents the energy level. Each value of n is associated with
an orbit of different radius.
Bohr accurately predicted the line spectrum of the hydrogen atom.
This work led to the planetary model of the atom, in which
electrons circle the atom's nucleus in fixed circular paths as
the planets do around the Sun.
