Question

5. Assertion (A): Copper (Z= 29) with electronic
configuration [Ar]4s1 310 is more stable than
[Ar]4s2 3d
Reason (R) : Copper with [Ar] 4s 3d10 is more
stable due to symmetrical distribution and
exchange energies of d electrons .
(1 Point)
A and R are correct and R is the correct
explanation of A
A and R are correct but Ris not the
correct explanation of A
O A is correct but R is wrong
A is wrong but R is correct​
