A) 786, 737, 577, 496
B) 496, 577, 786, 737
C) 496, 737, 577, 786
D) 496, 577, 737, 786
Correct Answer: C
Solution :
[c] Ionization energy of elements belonging to period III in general increases as we move from left to right with the exception of Group-2 and Group-15 elements due to their stable configuration. The increasing order of first ionization energy of the given elements is \[Na<Al<\text{M}g<Si\] Ionisation energy of the given metals are Na: 496 kJ/mol; Al: 577 kJ/mol Mg: 737 kJ/mol; Si: 786 kJ/molYou need to login to perform this action.
