K-between the first and second ionization energies

Ca-between the second and third ionization energies

Explanation:

Ionization energy is the energy required to remove an electron from a gaseous atom or ion. The first ionization energy of an atom is the energy required to remove one mole of electrons from one mole of isolated gaseous atoms.

The second ionization energy is usually greater in magnitude than the first ionization energy. However, when the electrons on the valence shell of the atom are exhausted, further ionization will involve the core electrons of the atom. This requires the removal of electrons from a completely filled Shell, this process requires a very large amount of energy. The energy required is far larger than the energy required to remove valence electrons from the outermost shell of the atom. This sudden tremendous increase in the magnitude of ionization energy as electrons are removed from a completely filled shell is known as a jump.

For calcium, a jump occurs after the second electron has been removed, the third electron must be removed from a completely filled inner shell. For potassium, a jump occurs after the first electron has been removed. The second electron must be removed from a completely filled inner shell.
