It has a full outer shell of electrons.
Lithium ====> Li , Electronic configuration { 1S2 2S1 } So we have only first ionization An the second will be from Complete stable energy level that need great amount of energy to remove it And that is impossible
You can ionize them under certain conditions. The difficulty is that the ionization energy is high as they have a stable octet.
When an element is in the gaseous state, it is the energy absorbed by that element to make one(the first) outer most electron leave the atom .
because neon is a noble gas which has stable electronic configuration ,but this is not the same in case of fluorine.This means we have to give high energy to gaseous neon atom to ionise it.
Ionization energy is the energy required to remove an electron from an atom. In the case of hydrogen, its one and only electron is very close to the nucleus, because it is in the first energy level (that electron's ground state.) So, the attraction between the nucleus (positive) and that electron (negative) is quite strong due to their closeness. As you move down group 1, the electrons get farther and farther away from the nucleus, and the attraction, predictably, decreases. This means lower ionization energy required the lower you go on the group.
Noble gases have completely filled orbitals are are stable. they do not donate electrons and hence are not included in ionization energy trend.

Ionization energy is defined as the energy required to make a stable atom into an ion.
You can ionize them under certain conditions. The difficulty is that the ionization energy is high as they have a stable octet.
This is called the ionization energy and an is different for each electron in the atom. Electrons in the outer shell (furthest from the nucleus) have the lowest ionization energy, electrons in the innermost shell (closest to the nucleus) have the highest ionization energy.
ionization!
When an element is in the gaseous state, it is the energy absorbed by that element to make one(the first) outer most electron leave the atom .
because when ionizing it from 3+ to 4+ it has only a filled orbital which is relatively stable (just as a noble gas). When you want to take away one more electron you do not end up with a filled orbital so this is less stable and will cost much more energy. The sixth ionization energy however should be quite low as well, because after that the carbon ion has no more electrons left which is also a reasonably stable state (compare to H+)
Organisms and rocks both contain stable and unstable elements.
It is difficult to remove electron from He than Li. LI easily loses electron and reach stable state.
because neon is a noble gas which has stable electronic configuration ,but this is not the same in case of fluorine.This means we have to give high energy to gaseous neon atom to ionise it.
The process of losing or gaining electrons to become stable is called ionization.
