SATHEE: Classification of Elements and Periodicity in Properties

Classification of Elements and Periodicity in Properties - Result Question 34

####34. Which of the following does not represent the correct order of the properties indicated [1997]

(a) $N i^{2 +} > C r^{2 +} > F e^{2 +} > M n^{2 +}$ (size)

(b) $S c > T i > C r > M n ($ size)

(c) $M n^{2 +} > N i^{2 +} < C o^{2 +} < F e^{2 +}$ (unpaired electron)

(d) $F e^{2 +} > C o^{2 +} > N i^{2 +} > C u^{2 +}$ (unpaired electron)

Show Answer

Solution:

(a) In a period on moving from left to right ionic radii decreases.

So order of cationic radii is $C r^{2 +} > M n^{2 +} > F e^{2 +} > N i^{2 +}$
