Ionisation energy of hydrogen is

Ionisation energy of hydrogen is

The ionisation energy of electron (E) is second orbit of hydrogen atom is

Which of the following cannot be the value of ionisation energy for a hydrogen atom ?

Using Bohr's formula for energy quantization, the ionisation potential of first excited state of hydrogen atom is

The second ionisation energies are higher than the first ionisation energies. This is mainly due to the fact that after the removal of the first electrons, the atom changes inot mono valent position ion. In the ion, the number of electrons decreases but the nuclear charge remains the same. As a result of this, the remaining electrons are held more tightly by the nucleus and it becomes difficult to remove the second electron . Therefore, the value of second ionisation energy . (IE_(2)) , is greater than that of the first ionisation energy (IE_(1)) . Similarly third ionisation energy (IE_(3)) is greater than that of second IE_(2) . Successive ionisation energy of an atom is greater than previous one, because

The ionisation energy of 10 times innised sodium atom is

As one considers orbits with higher value of n in a hydrogen atom, the electron potential energy of the atom
