The ionization energy will be higher when the electron is removed from .........if other factors being equal.

The minimum amount of energy which is required to remove an outermost electron from any isolated neutral gaseous atom is known as first ionisation energy. These are the following factors which effect ionisation energy. (i) Ionisation energy prop (1)/("Principal quantum number") (ii) Ionisation energy prop Z_(eff) (iii) If orbitals are fully filled or half filled so stability will be more and ionisation energy will be high. (iv) If penultimate electron will effectively shield the nucles, ionisation energy will be less and vice versa. Choose the correct order of Ist ionisation energy

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 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. IE_(1) and IE_(2) of Mg metal are 178 and 348 kcal/mol respectively. the energy required for the given reaction is: Mg(s) to Mg^(+2)+2e^(-)
