1.	Which of the following is generally true.A: Atomic size increases from left to right across a period. B: Ionization potential increases from left to right across a period.C: Electron affinity increases on going down a group. D: Electronegativity increases on going down a group.
Answer» Atomic size DECREASES from left to right ACROSS a period. Electron affinity decreases on going down a GROUP. Metallic character decreases from left to right across a period. ELECTRONEGATIVITY increases on going down a group. Solution :Electronegativity increases on going down a group.
