Why is the second ionisation energy of an element much greater than its first ionisation energy ?

Why are the second ionisation enthalpies of group 1 elements much higher than their first ionisation enthalpies ?

Which has the largest first ionisation energy ?

Ionisation energy of hydrogen is

Ionisation energy of hydrogen is

Why is the ionisation energy of beryllium greater than that of Li and B?

The second ionisation enthalpy of an alkaline earth metal is higher than its first ionisation enthaply. Why is it so ?

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 second ionisation enthalpies of elements are always higher than their first ionisation enthalpies because:

The second ionisation energies are higher than the first ionisation energies. This is mainly due to the fact the after the removal of the first electron, the atom changes into monovalent positive 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 ionisatio energy (IE_(1)) . similarly third ionisation energy (IE_(3)) is greater than that of second IE_(2) . Q. Successive ionisation energy of an atom is greater than previous one, because:
