Select which periodic property is not regular in halogen family moving down thegroup?

Select the correct set of statements regarding change in properties, as we move down the second group in periodic table. (I) Atomic size increases. (II) Electronegativity increases. (III) Tendency to loose electrons increases. (IV) Valency remain same.

In which of the following options order of arrangement does not agree with the variatioin of property indicated against it? Thinking process. i) The ionic size increases as the positive charge on the cation decreases or the negative charge on the anion increases. ii) First ionisation enthalpy increases from left to right in the periodic table. iii) Electron gain enthalpy increases as the electronegativity of the atom increases. iv) The metallic character increases as the size of the metal atom increases.

The properties of the elements such as atomic or ionic radii ionisation enthalpy, electron gain enthalpy and electronegativity are directly or indirectly related to their electronic configuration and are called periodic properties. A part the periodic table is given below : {:(C, N, O, F),(, P, S, Cl),(,,Se, Br), (,,,I):} Which of the following has the largest size ?
