How many protons and neutrons does boron-11 have?


Boron-11 is a chemical element that has five protons and six electrons. It is an uncommon element that is rarely found in the Earth's crust or atmosphere.

Boron-11 is produced in the universe through naturally occurring nuclear fission and nucleosynthesis called cosmic ray spallation. To discover the amount of protons and neutrons in boron-11, one must look at its atomic number and atomic mass. Boron-11's atomic number is five, which means it always has five protons. To discover how many electrons boron-11 has, one should subtract the amount of known protons from its atomic mass of 11. The remainder, six, represents the electrons present in the chemical element.
