4 days ago · Density functional theory (DFT) is a computational quantum mechanical modelling method used in physics, chemistry and materials science to investigate the electronic structure (or nuclear structure) (principally the ground state) of many-body systems, in particular atoms, molecules, and the condensed phases.
1 day ago · To transition downward, an electron must lose energy, causing it to emit a photon. The exact amount of energy lost or gained depends on what levels the electron transitions between. For example, in the diagram below, an electron drops from the 2nd energy level, 𝐸 , to the ground state 𝐸 .
2 days ago · The van der Waals equation, named for its originator, the Dutch physicist Johannes Diderik van der Waals, is an equation of state that extends the ideal gas law to include the non-zero size of gas molecules and the interactions between them (both of which depend on the specific substance).
