# What is the total charge of the nucleus of a nitrogen atom?

Of a nitrogen nucleus.............the total electronic charge is $+ 7 \times 1.602 \times {10}^{-} 19 \cdot C = 1.12 \times {10}^{-} 18 \cdot C$............
The total electronic charge is $+ 7$. How do we know? Well, the atomic number of nitrogen is $7$, which specifies 7 fundamental, nuclear particles with a positive charge. Of course, electronic charge is balanced by 7 fundamental extranuclear particles with negative charge, 7 electrons conceived to whizz about the nuclear core. In ""^14N what other nuclear particles do we have to consider?
