Proton | Electron | Charge |
23 | X | +3 |
46 | 43 | Y |
A) \[20,-3\]
B) \[20,+3\]
C) \[26,-3\]
D) none of these
Correct Answer: B
Solution :
Atomic number = number of protons No. of electrons in positive ion = no. of proton - no. of \[+ve\] charge on ion No. of electrons in negative ion = no. of- proton + no. of \[-ve\] charge on ion (No. of electrons) \[X=23-3=20\] (No. of charge) \[Y=46-43=+3\]You need to login to perform this action.
