Question

Quizplus · Accepted Answer

In an electrically neutral atom, the number of protons (positively charged particles in the nucleus) is exactly balanced by the number of orbital electrons (negatively charged particles that orbit the nucleus), ensuring electrical neutrality. Quarks are constituents of protons and neutrons, and neutrons are neutral particles in the nucleus that do not affect the electrical charge balance.
