Statement (i) Na ₂ O Cl > Br-Electron gain enthalpy (iii) M²⁻>M⁻>M⁺>M²⁺ -ionic size (iv) The second ionisation enthalpy of Cu is more than second ionisation enthalpy of K . Which of the following is the correct representation of True ( T ) / False ( F ) for the given statements?

Step-by-step solution

(i) Acidic property increases with the increase in oxidation number of the central atom (element) and for same oxidation number acidic nature increases along the period (according to long form periodic table). So, this statement is correct. (ii) Electro gain enthalpy for Cl is more (-)ve than of F (due to extremely small size of F -atom) and electron gain enthalpy for Br-atom is less (-) ve than of Cl -atom (due to its larger size). Hence, the statement in false. (iii) If any ion accept the electron, ionic size wil
