A deep-space nanodrone scans a single neutral atom captured from an interstellar cloud. Its instruments reveal a dense central core containing 11 positively charged protons and 12 neutral particles called neutrons. To verify electrical neutrality, the drone's sensors scan the vast region surrounding the nucleus for the balancing subatomic particles. Which description correctly identifies these outer particles and their properties?

A) They are protons residing in concentric outer energy levels, each possessing a relative charge of $+1$.

B) They are electrons distributed outside the nucleus, each possessing a relative charge of $-1$.

C) They are neutrons orbiting the central core at high speed, each possessing an electrical charge of $0$.

D) They are electrons packed tightly within the central core, each possessing a relative charge of $-1$.
