The ionization energy tells us about the energy required (and thus the ease) with which an atom/ion can give away an electron (in the outermost shell).
So, atoms with low ionization energies ( lowest for Caesium) give away the electron with ease
The outer shell is called the valence shell
Yes, an electron in the outermost energy level of an atom is called a valence electron. Valence electrons are involved in chemical bonding and determining the reactivity of an atom.
Cesium, or Cs, has 1 valence electron.
Helium has the highest ionization energy due to its stable electron configuration, requiring a lot of energy to remove an electron. In contrast, francium has the lowest ionization energy because it is the least electronegative element and its outer electron is the furthest from the nucleus, making it easier to remove.
No, the ionization energy of sodium is not the same as chlorine. The ionization energy of sodium is lower than that of chlorine because sodium requires less energy to remove an electron. Sodium has a single electron in its outer shell, while chlorine has seven electrons in its outer shell, making it harder to remove an electron.
Helium has a larger ionization energy compared to lithium. This is because helium has a full valence shell, making it more difficult to remove an electron compared to lithium, which has only one electron in its outer shell.
Ionization energy and electron affinity for cations and anions, respectively.
Valence electrons.
IONIZATION enthalpy is the amount of energy to lose electron from its outer most shell .

In contrast, francium has the lowest ionization energy because it is the least electronegative element and its outer electron is the furthest from the nucleus, making it easier to remove.
Briefly, it is the energy required to completely remove a valence (outer shell) electron from its atom when forming an ionic bond.See related links below for more info
The electrons on the outtermost energy level of an atom is called a valence electron.
