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.
Which of the following elements has the lowest first ionization energy?
Following the trend, it makes sense that the element with the lowest first ionization energy would be the lowest, leftmost element, Francium.
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.
Why does ionization energy decrease down the periodic table?
If you follow the general trend on the periodic table, you see that ionization energy decreases down a period because as electrons are added to higher octets, the average distance of the electron from the nucleus increases and screening by inner electrons increases.
