Account for the following: Noble gases have large positive electron gain enthalpies.

a) The electron gain enthalpies of Be and Mg are positiVe. What is your opinion? Justify. b) Electron gain enthalpies of nobles gases have large positive values. Why?

Generally electron gain enthalpy increases along a period and decreases down the group. But electron gain enthalpy of oxygen is -141 kJ//mol while that of sulphur is -200 kJ//mol . Explain.

X, Y and Z are three elements with atomic numbers (x-1), x and (x+1) respectively. If Y is a noble gas answer the following. Among X, Y and Z which would have positive value for electron gain enthalpy? Why?

The physical and chemical properties of elements are periodic functions of their atomic numbers. a) The atomic number of an element 'X' is 19. Write the group number, period and block to which 'X' belong in the periodic table. b) Name the element with i) highest electronegativity and ii) highest electron gain enthalpy
