A particle detector is set to select only ions with a relative mass of 23 and a total relative charge of +1.
The table shows the particles in four possible records.
| Record | Protons | Neutrons | Electrons |
|---|---|---|---|
| F | 11 | 12 | 10 |
| G | 11 | 12 | 12 |
| H | 12 | 10 | 11 |
| J | 12 | 11 | 12 |
Take the relative mass of each proton and each neutron as 1, and treat the mass of the electrons as negligible.
Which record is for an ion that the detector will select?
Record J
Record F
Record G
Record H
