A carbon-14 atom is singly ionised by losing an electron to form a 614C+^{14}_{6}\text{C}^{+}614C+ ion.
Which row in the table correctly describes the composition and net charge of this ion?
| Number of protons | Number of neutrons | Number of electrons | Net charge / C\text{C}C | |
|---|---|---|---|---|
