Question

Quizplus · Accepted Answer

The number of subatomic particles in an atom is determined by the number of protons, neutrons, and electrons. The atomic number, which is the number of protons in an atom, is the same for all atoms of the same element. In option B, both atoms have the same number of protons (atomic number 5 for boron) and the same number of electrons (5) since they are both neutral atoms. Therefore, they have the same number of subatomic particles.
