What family has the lowest ionization energy?
What family has the lowest ionization energy? The alkali metals……….. Group 1 of the Periodic Table features metals whose valence electron SINGLY occupies the outermost shell, the valence shell of the given atoms.
Why do alkali metals have the lowest ionization energies?
Since the nuclear charge is necessarily diminished with respect to the valence shell, the alkali metals display the lowest ionization energies, and these energies (reasonably) decrease down the Group. But a chemist, a physical scientist should examine the data.
What is the ionization energy measured in?
Note: The ionization energy is measured in joules (J) or electron volts (eV). The values mentioned in the chart are given in electron volts (eV).
