What will be the charge on a 7n14 nucleus?

The charge on a (^{7}{14}\text{N}) nucleus can be determined by looking at its atomic number and mass number. The atomic number (7) indicates that it has 7 protons, which means the charge is +7, as protons are positively charged. The mass number (14) indicates the total number of protons and neutrons, but it does not affect the charge. Thus, the charge on a (^{7}{14}\text{N}) nucleus is +7.
