For helium, it is 4: two … WebAug 19, 2024 · The atomic mass of Boron is 10.811, rounded off to 11. And the number of protons in Boron is 5. therefore, the number of neutrons in a boron atom is 11 – 5 = 6. The number of electrons in any neutral atom equals the number of protons. Since the Boron atom is neutral, its electrons will equal the number of its protons.
