the atomic model which is based on the particles and wave nature of the electron is known as wave mechanical model of the atom.

this model describes the electron as a three-dimensional wave in the electronic field of positively charged nucleus .

schrodinger study electron wavelengths in order to build his theory.

In the solution to the Schrödinger equation, which is non-relativistic, hydrogen-like atomic orbitals are eigenfunctions of the one-electron angular momentum operator L and its z component Lz. A hydrogen-like atomic orbital is uniquely identified by the values of the principal quantum number n, the angular momentum quantum number l, and the magnetic quantum number m. The energy eigenvalues do not depend on l or m, but solely on n. To these must be added the two-valued spin quantum number ms = ±½
