A system of 11 protons and 15 neutrons has a net charge of

Question

Quizplus · Accepted Answer

The net charge of a system is the sum of the charges of all the particles in the system. In this case, we have 11 protons, each with a charge of +1e, and 15 neutrons, each with a charge of 0e. Therefore, the net charge of the system is:$$11e + 15(0e) = 11e$$where e is the elementary charge, which is equal to 1.602 × 10^-19 C. Therefore, the net charge of the system is:$$11e = 11(1.602 × 10^-19 C) = 17.6 × 10^-19 C$$Therefore, the correct answer is A.
