Computational methods electronic structure

How do you calculate electronic structure?
The electronic structure of an atom can be predicted from its atomic number.
For example, the atomic number of sodium is 11.
Sodium atoms have 11 protons.
The relative charge of a proton is +1..
How do you determine the electronic structure of an atom?
Electron configurations and orbital diagrams can be determined by applying the Pauli exclusion principle (no two electrons can have the same set of four quantum numbers) and Hund's rule (whenever possible, electrons retain unpaired spins in degenerate orbitals)..
What are the methods of electronic structure calculation?
Some popular electronic structure methods include DFT[8–10], Hartree–Fock (HF) method [11,12], Quantum Monte Carlo [13–15], coupled cluster [16,17], multireference configuration interaction [18], etc..
What is electronic structure method?
The term encompasses both the wave functions of the electrons and the energies associated with them.
Electronic structure is obtained by solving quantum mechanical equations for the aforementioned clamped-nuclei problem.
Electronic structure problems arise from the Born–Oppenheimer approximation..
Why is electronic structure important?
Electron configurations provide insight into the chemical behaviour of elements by helping determine the valence electrons of an atom.
It also helps classify elements into different blocks (such as the s-block elements, the p-block elements, the d-block elements, and the f-block elements)..

Electronic structure methods are characterized by their various mathematical approximations to its solution. There are two major classes of electronic structure methods : Semi-empirical methods. These methods use parameter derived from experimental data to simplify the computation.

In this thesis, stochastic methods for the solution of Schrödinger's equation are developed and applied to real systems. Quantum Monte Carlo (QMC) methods treat

State of motion of electrons in an electrostatic field created by stationary nuclei

In physics, electronic structure is the state of motion of electrons in an electrostatic field created by stationary nuclei.
The term encompasses both the wave functions of the electrons and the energies associated with them.
Electronic structure is obtained by solving quantum mechanical equations for the aforementioned clamped-nuclei problem.
