Classification of Elements and Periodicity in Properties: NEET questions with solutions
NEET tests systematic names for Z above 100, locating an element from its configuration, and the periodic trends in radius, ionization enthalpy, electron gain enthalpy and oxide character. Marks are lost on the exceptions: B below Be and O below N in ionization enthalpy, Al below Mg, and Cl (not F) having the most negative electron gain enthalpy.
