Question Answer
Louis De Broglie wave properties, paricles can behave like waves, waves behave like particles
Werner Heisenberg impossible to determine the exact position and velocity of an electron at the same time; called the Heisenberg uncertainty principle
Erwin Schrodinger with his equation, we can find the place where the electrons are likely to be
Quantum Theory quantum mechanical model, electrons do not move in definite paths, impossible to determine the exact location of an electron, the probable location is based on the energy it has, finding an electron in a certain area called an atomic orbital
S orbital 0, sphere shaped
P orbital 1, dumbbell shaped ( 3 orbitals)
D orbital 2, blowing up balloons, 5 orbitals
F orbital 3 (7 orbitals)
n principle quantum # (energy level, cannot be 0)
l angular momentum quantum # (type of orbital) s=0 p=1 d=2 f=3
ml magnetic quantum # (orientation)
ms spin amount quantum # (spin of electron)
degenerate same energy
Order 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 5d, 4f, 6p
Anything in the D sublevel is? counted an energy level lower
