Potassium has a low ionization energy.
The ionization energy of aluminium is 5,985 77 eV. It is a medium energy.
ionization potential energy. but remember the atom must be neutral .
The fewer numbers of valence electrons, and the farther away those valence electrons are from the nucleus, the lower the ionization energy will be. So your group 1 and 2 metals toward the bottom of those groups will have low ionization energies, and therefore be very reactive.
Francium has a very low ionization energy, making it one of the most reactive elements. It readily loses its outermost electron to form a positive ion.
Low
Potassium has a low ionization energy.
high
The ionization energy of aluminium is 5,985 77 eV. It is a medium energy.
low ionization energy
Sodium has a relatively low ionization energy, as it only requires a small amount of energy to remove an electron from a sodium atom. This is because sodium has one electron in its outermost shell, which makes it relatively easy to remove.
The electrons in actinium are disposed on seven energy levels.
no
Yes, nonmetals typically have a low first ionization energy compared to metals. This is because nonmetals have higher electronegativity and tend to gain electrons rather than lose them when forming ions, resulting in a lower energy requirement to remove an electron from a nonmetal atom.
Actinium has seven electron shells.
