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 proton No. of electron in positive ion = no. of proton?charge No. of electron in negative ion = no. of proton + charge (No. of electron) \[X=23-3=20\] (No. of charge) \[Y=46-43=+3\]You need to login to perform this action.
