Atom Flashcards
Coulomb Force is balanced by the centripetal force
The angular momentum of the electron in an allowed orbit is quantized
Transition of an electron between energy levels is accompanied by emission or absorption of a photon with energy equal to lost or gained orbital energy
Absorption Energy Level
Emission Energy Level
Radius of the Bohr atom (long)
Radius of the Bohr atom (short)
Plancks Constant (Js)
mass of an electron (kg)
charge of an electron (C)
Velocity of the Bohr Electron (long)
Velocity of the Bohr Electron (short)
Total Energy of the Electron (Bohr Model)
Electron Volt to Joules
If the total energy of an electron is negative
it is “bounded”
Ionization Energy
The energy needed to remove the electron completely from the atom. (Energy must be greater than or equal to zero.)
Rydberg constant (1/m)
Line Spectrum of an atom
Lyman Series
Balmer Series
Paschen Series
Brackett Series
Emission Lines
The spectral lines that are produced when electrons transit from higher energy levels to lower energy levels
Absorption Lines
The spectral lines that are produced when the electron transit from the lower energy levels to the higher levels by absorbing energy
Total angular momentum of system of nucleus and electron
De Broglie and Bohr Angular Momentum
Reduced Mass of the system

Zeeman Effect
the externally applied magnetic field can split the energy levels of the atom

Energy Level Hierarchy
The Pauli Exclusion Principle
No two electrons in an atom can have the same set of quantum numbers (n,l,ml,ms)
