A neutral atom has equal numbers of:
AElectrons and neutrons
BProtons and neutrons
CAtoms and molecules
DProtons and electrons
Answer & Solution
Correct answer: D. Protons and electrons
A neutral atom has equal numbers of POSITIVE protons (in the nucleus) and NEGATIVE electrons (orbiting outside), so the total charge is zero. The number of neutrons is unrelated to neutrality — it varies among isotopes of the same element.
