The quantum mechanical model of atoms describes the three-dimensional position of the electron in a probabilistic manner according to a mathematical function called a wavefunction, often denoted as ψ. Atomic wavefunctions are also called orbitals.
21 Νοε 2023 · The wave-mechanical model is a current theory describing the locations of electrons in orbit around the nucleus of an atom. The model proposes that there are up to 7 principal energy levels...
The quantum (wave) mechanical model of the atom was devised. Electrons occupy orbitals, which are probability fields or spaces around the nucleus of an atom where an electron is likely to be found. Important criteria was established in developing this modern atomic theory:
12 Ιουλ 2023 · In 1926, an Austrian physicist, Erwin Schrödinger (1887–1961; Nobel Prize in Physics, 1933), developed wave mechanics, a mathematical technique that describes the relationship between the motion of a particle that exhibits wavelike properties (such as an electron) and its allowed energies.
Proposed by Austrian physicist Erwin Schrodinger in 1926, the wave mechanical model is a complex mathematical description of the atom and its electrons. The x-dimension version of the Schrodinger wave equation is shown at the right. There is also a y-dimension and z-dimension equation.
Quantum mechanics is based on Schrödinger’s wave equation and its solution. The solution of the wave equation brings the idea of shells, sub-shells and orbitals. The probability of finding an electron at a point within an atom is proportional to the |ψ| 2 at that point, where ψ represents the wave-function of that electron.
The modern model that Schrödinger ushered in is known as the wave-mechanical model of the atom. By solving the Schrödinger equation, it is possible to determine the energy levels and the most probable location, from the nucleus, of an electron in each energy level.
