In physics and chemistry, ionization energy, or ionisation energy is the minimum energy required to remove the most loosely bound electron of an isolated gaseous atom, positive ion, or molecule. The f
These electron configurations do not show the full and half-filled orbitals.
Here the added electron has a spin opposed to the other 2p electrons. This decreases the ionization energy of oxygen
Because of a single p-orbital electron in gallium's configuration, makes the overall structure less stable, hence the dip in ionization energy values
Actinium's electron configuration predetermines that it would require less energy to remove that single d-orbital electron, therefore even though it has a larger EC, radium still has the higher IE
In quantum mechanics, an atomic orbital is a function describing the location and wave-like behavior of an electron in an atom. This function describes an electron's charge distribution around the ato
Ionization energy
…Hydrogen's ionization energy is very high (at 13.59844 eV), compared to the alkali metals. This is due to its single electron (and hence, very small electron cloud), which is close to the nucleus. Likewise, since there are not any other electrons that may cause shielding, that single electron experiences the full…
