A) \[Na<Mg>Al<Si\]
B) \[Na>Mg>Al>Si\]
C) \[Na<Mg<Al<Si\]
D) \[Na>Mg>Al<Si\]
Correct Answer: A
Solution :
In a period the ionization potential generally increases from left to right but the ionization potential of II A group is higher than III A due to stable electronic configuration. Hence, the order of ionization potential of Na, Mg, Al and Si is as: \[Na<Al<Mg<Si\] or \[Na<Mg>Al<Si\] (5.1) (7.6) (6.0) (8.1)You need to login to perform this action.
