how many neutrons are found in boron
Boron has five protons, and assuming it's not an ion, five electrons. The number of neutrons depends on the isotope. It can have anywhere from 2 to 14 neutrons, although only the isotopes with 5 or 6 neutrons is stable. Boron 11 (with 6 neutrons) is 80% of the boron found in nature, boron 10 (with 5 neutrons) is 20% of the boron found in nature. Source(s): The CRC Handbook of Chemistry and Physics, 79th Edition.
