Question

Quizplus · Accepted Answer

The net charge of a system is the total charge of all the particles in the system. In this case, the system has 11 protons and 9 neutrons. Protons have a charge of +1e, while neutrons have a charge of 0e. Therefore, the total charge of the system is 11e + 9(0e) = 11e. The charge of an electron is -1.602 x 10^-19 C, so the net charge of the system is 11e * -1.602 x 10^-19 C = -17.6 x 10^-19 C.
