Answer: de Broglie.
- A Heisenberg
- B de Broglie
- C Schrodinger
- D Bohr
Correct answer: B. de Broglie
Explanation: Louis de Broglie proposed that every moving particle has an associated wavelength given by lambda = h/mv, establishing the dual nature of matter.
Bohr's model: electrons occupy fixed circular shells (K, L, M) around the nucleus, with each shell holding up to 2n2 electrons.
