…………. and most stable species is ………………

(A) 4, 3 and 2 and V3+ is most stable (B) 3, 3 and 2 and Cr3+ is most stable

(C) 4, 3 and 2 and Cr3+ is most stable (D) 3, 7 and 3 and Mn3+ is most stable​

Answer 1

Answer:

Mn3+

Explanation:

Mangenese is more stable than other gaseous state

Answer 2

Answer:

(A) 4, 3 and 2 and V3+ is most stable

Explanation:

Mn3+= [Ar]3s23d2

Cr3+=[Ar]3s23d1

V3+=[Ar]3s2
