Does helium have the largest first ionization energy of all the elements?

No, helium does not have the largest first ionization energy of all the elements. Helium actually has the highest first ionization energy of any element, due to its small atomic size and stable electron configuration.


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.

Fluorine. Ionization energies are a periodic trend and they generally increase as you go up and to the right in the periodic table.See the chart in the Web Links to the left for a complete chart of the ionization energies of all the elements.


What has the highest first ionization energy phosphorous calcium sodium or aluminum?

Phosphorus has the highest first ionization energy among phosphorus, calcium, sodium, and aluminum. This is because phosphorus has a higher effective nuclear charge compared to the other elements, making it more difficult to remove an electron from its outer shell.
