The Quantum Model of an Atom

The Quantum Model of an Atom

1. Electrons have wave-like properties

   • Investigations into the photoelectric effect & hydrogen's emission line spectrum have revealed that light can behave as both a wave and particle.
   • French scientist Louis de Broglie suggested that electrons be considered waves confined to the space around an atomic nucleus.

2. The speed and position of an electron cannot be measured simultaneously.

   • the idea of electrons having a dual wave-particle nature troubled scientists.
