Question

what is the mean of electron configuration? ​

Answer 1

Answer:

Electronic configuration, also called electronic structure, the arrangement of electrons in energy levels around an atomic nucleus. ... In terms of a more refined, quantum-mechanical model, the K–Q shells are subdivided into a set of orbitals (see orbital), each of which can be occupied by no more than a pair of electrons.
