Respuesta :
if all of the eg orbitals are filled, can an electron from the t2g level be promoted to the eg level by the absorption of a photon of visible light. No it is not possible.
A mathematical expression known as an orbital, or wave function, describes the properties of no more than two electrons in the vircinity of an atomic nucleus or of a system of nuclei, such as in a molecule. the four fundamental types of orbitals. Two electrons can fit into an orbital, which is spherical in shape. There are three orbitals, each with the same fundamental shape but varying in their spatial orientation.
A photon is an elementary particle that functions as both the force carrier for the electromagnetic force and a quantum of the electromagnetic field, which includes electromagnetic radiation like light and radio waves. Since photons have no mass, they always travel at the speed of light in a vacuum.
