Question
Which of the following represents the correct trend for the mentioned property ? A. F > P > S > B – Frist Ionization Energy B. Cl > F > S > P – Electron Affinity C. K > Al > Mg > B – Metallic character D. K2O > Na2O > MgO > Al2O3 – Basic character Choose the correct answer from the option given below. (A) A, B and D only (B) A, B, C and D (C) A and B only (D) B and C only
💡 Solution & Explanation
On moving left to right in a period IE increases and from top to bottom in a group IE decreases. F > P > S > B (IE order) On moving left to right in a period metallic and basic character decreases. K > Mg > Al > B (Metallic character order) On moving top to bottom in a group metallic and basic character increases. K2O > Na2O > MgO > Al2O3 EA : Group 17 > Group 16 > Group 15 Cl > F > S > P
