(a). Why IE_1 of Zn , Cd and Hg are very high? (b). The relative difference in IE of any two consecutive d-bloch elements is smaller than those of s and p-block elements. (c). IE_2 is usually very high for Cr and Cu . Why?

The energy required to remove an electron from the outermost shell of an isolate gaseous atom is known as IE_(1) of that atom. Similarly, the enrgy required for the removal of the electron from the unipositive ion, diapositive ion and tripositive ion are known as IE_(2),IE_(3) and IE_(4) respectively, and are called successive ionisation energies. The magnitude of the charge depends on the size of the orbital of electron. Electrons in smaller orbitals are on average close with each other and have more repulsion. Thus for Be(2s^(2)) , the IE_(1) and IE_(2) are 9.3 and 18.2 eV "atom"^(1) , whereas for Ca(4s^(2)) , the values are 6.1 and 11.9 eV . The relationship between IE_(4) and IE_(2) of an element is

Difference between the greatest and the least values of the function f(x)=x(ln x-2) on [1,e^2] is

Ionisation energy is the amount of energy required to remove the outermost e^(-) from a gaseous atom. It's unit is kJ/mole or kcal/mole. Successive ionisation energy - It is the amount of energy required to remove electron successively from a gaseous ion. These are termed as IE_(2), IE_(3), IE_(4) etc. the difference in the values of IE_(1), IE_(2) " and " IE_(3) helps to determine electronic configuration of the element. Which of the following is a non-metal ?
