I. \[_{\text{48}}^{\text{114}}\text{Cd}\] and \[_{50}^{\text{119}}\text{Sn}\] |
II. \[_{\text{27}}^{\text{59}}\text{Co}\] and \[_{\text{28}}^{\text{59}}\text{Ni}\] |
III. \[_{\text{55}}^{\text{133}}\text{Cs}\] and \[_{\text{54}}^{\text{132}}\text{Xe}\] |
IV. \[_{\text{29}}^{\text{63}}\text{Cu}\] and \[_{\text{29}}^{\text{65}}\text{Cu}\] |
A) I and IV only
B) I and III only
C) III only
D) IV only
Correct Answer: C
Solution :
Number of neutrons in Cd = 66, Sn = 69; Co = 32, Ni = 31 Cs = 78, Xe = 78; \[^{\text{63}}\text{Cu=34}\], \[^{\text{65}}\text{Cu=36}\]You need to login to perform this action.
