Low lying empty orbitals
WebThe orbital for which the value of (n + l) is lower is the low energy orbital and the electron will enter that orbital first. Orbital: Orbit (n) Azimuthal quantum number (l) Orbital energy (n + l) 3d: 3: 2: 5: 4s: 4: 0: 4: Energy of orbital. Here, … WebLow-lying means the orbital has a low energy associated with it when there is an electron in it. Vacant means there is no electron in it. So, for example, an excited hydrogen atom may have its electron in an n=4 orbital.
