What is electronic configuration?
Also called electronic structure, the arrangement of electrons in orbits around the nucleus. The electron configuration of atoms in quantum mechanical models is given by ordering the occupied orbitals in order of packing, with the number of electrons in each orbital indicated as a superscript.
What is atomic number?
The atomic number, or atomic number of a chemical element, is the number of electric charges in the nucleus. For normal atomic nuclei, this equals the number of protons, or the number of protons found in the nucleus of each atom of that element. Atomic numbers can be used to uniquely identify common chemical elements.
