Within each pair of element F & Cl s & se, and Li & Na , respectively , the elements that release more energy upon electron gain are

If the ionization enthalpy and electron gain enthalpy of an element are 275 and 86 kcal mol^(-1) respectively, then the electronegativity of the element on the Pauling scale is

The binding energies of the atoms of elements A and B are E_(a) and E_(b) , respectively. Three atoms of the element B fuse to give one atom of element A. this fusion process is accompanied by release of energy e. then, E_(a),E_(b) are e are related to each other as

Of the two elements given in each of the following cases, choose the element having a more negative electron gain enthalpy. Explain. F and Cl

Which of the following pairs of elements would have more negative electron gain enthalpy.

Of the two elements given in each of the following cases, choose the element having a more negative electron gain enthalpy. Explain. N and O

Consider the following elements B C F Cl N O If x,y and z are the number of elements having more electron affinity (Ea_(1)) than nitrogen, the number of elements having ionisation energy more than that of Na and the number of elements having electronegativity more than (or) almost equal to N respectively, find x+y+z . Fill your answer as sum of digit (excluding decimal places) till you get the single digit answer.
