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

What is larger ionization energy?

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.

What elements have the highest and lowest ionization energy?

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.


What is ionization energy?

The electrons on the outtermost energy level of an atom is called a valence electron.


Is the ionisation energy of sodium same as chlorine?

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.
