Boron has an atomic number of 5, which means it has 5 protons in its nucleus. To find the number of neutrons in an atom, we can use the formula:
Number of Neutrons = Atomic Mass – Atomic Number
The most common isotope of boron is Boron-11, which has an atomic mass of approximately 11. Therefore, we can calculate:
Number of Neutrons = 11 – 5 = 6
So, each atom of boron typically contains 6 neutrons. Among the options provided, the correct answer is b) 6.
