Atomic Structure
Learners explain historical findings such as Rutherford and Bohr's contributions, explain wave particle duality, and formulate Heinsenberg's uncertainty principle. They also draw s, p, and d orbitals, explain more historical findings,...

Pbs: People & Discoveries Niels Bohr
A wonderful PBS biography of a great man. This contains many personal touches, yet does a fine job of describing Bohr's scientific work. But it's best at Bohr the man. Nice quotes, one in the middle, one at the end.
