Statement 1 : The electron gain enthalpies have large negative values towards the upper right of the periodic table preceding the noble gases. Statement 2 : The effective nuclear charge increases from left to right across a period and consequently it will be easier to add an electron to a smaller atom since the added electron on an average would be closer to the positively charged nucleus.

How does ionisation enthalpy of the elements very as we move across the period from left to right ?
