Niels Bohr developed a model which states that electrons are in discrete ______________. 2. An electron infinitely far from the nucleus has an energy state of _____________________. 3. As electrons get closer to the nucleus, they move to a ________________ energy state. 4. Excited electrons in a higher energy level come back to the ground state and release _______. ELECTRONS and ORBITALS 1. de Broglie : “An electron behaves like a ________________ and a ______________.” E = hc/ c =  = h /mv 2. Schrödinger : “The electron is assumed to behave as a ____________________________.” ( p)( x) ≥ h /4 Ĥ = E 3.
