Among the following, the correct statement/s about 'p' block elements is/are I. The valence shell electronic configuration of all of them is ns ^2 np ¹⁻⁶ II. Only in p block, metals, nonmetals and metalloids are present III. Halogens have the lowest negative electron gain enthalpy in the respective periods IV. Noble gases have no tendency to accept an electron and hence they have large negative values of electron gai
