Why 1st ionization energy of Li is lower than that of Hydrogen?

1st ionization energy is the energy to remove one electron from a neutral atom. 2nd ionization energy is the energy to remove an electron from a positively charged ion. When this is done there is a stronger attraction for electrons in the ion than in the neutral atom because there is one less electron to 'interfere' with the electron being removed.


Of the following elements which one would have the largest ionization energy Hydrogen (H atomic 1) Cesium (Cs atomic 55) Sodium (Na atomic 11) Potassium (K atomic 19)?

Cesium (Cs) would have the largest ionization energy because it is the element with the highest atomic number in the list. As you move across a period from left to right, the ionization energy generally increases due to increasing effective nuclear charge. Therefore, Cesium would have the highest ionization energy followed by Potassium, Sodium, and then Hydrogen.

What is magnesium ionization energy?

The magnesium ionization energy is the amount of energy required to remove one electron from a neutral magnesium atom to form a positively charged magnesium ion. The first ionization energy of magnesium is 737.7 kJ/mol, indicating the energy needed to remove the outermost electron.

What is second ionization energy of hydrogen?

hydrogen has only one electron so after you remove that electron you do not have any electrons left to remove so hydrogen doesn't have a 2nd ionization energy. hydrogen has 1 proton and 1 electron.
