The Balmer series or Balmer lines in atomic physics, is the designation of one of a set of six different spectral emission lines of the hydrogen atom whose energy levels can calculated using an empirical equation discovered by Johann Balmer in 1885. Later Neils Bohr sought to explain them by using the Rutherford model of … Read more
Quantum mechanics defines the spatial orientation of electrons in atoms only in terms of the probabilistic values associated with Schrödinger wave equation. In other words in a quantum system Schrödinger wave equation plays the role of Newtonian laws in that it predicts the future position or momentum of a electron in terms of a probability … Read more
The Pauli Exclusion Principle is the quantum mechanical principle that says that two identical fermions (particles with half-integer spin) cannot occupy the same quantum state simultaneously. Presently it is defined in the terminology of quantum mechanics as when the wave function for two identical fermions is anti-symmetric with respect to exchange of the particles. In … Read more
