Electron Configuration Chart Aluminum. An electron configuration can quickly and simply tell a reader how many electron orbitals an atom has as well as the number of electrons populating each of its orbitals. The content that follows is the substance of general chemistry lecture 26.
N atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. A neutral atom of aluminum has 13 protons and 13 electrons. An electron configuration can quickly and simply tell a reader how many electron orbitals an atom has as well as the number of electrons populating each of its orbitals.
This means part of the electron configuration has been replaced with the element symbol of the noble gas symbol.
