Boron, as an element, is composed of three fundamental subatomic particles: protons, neutrons, and electrons. Protons, carrying a positive charge, reside in the nucleus of the atom, while neutrons have no charge and accompany protons in the nucleus. Electrons, on the other hand, possess a negative charge and orbit the nucleus. Understanding the number of each of these particles is crucial for characterizing and understanding boron’s atomic composition.
