The most common isotope of boron is boron-11, which has an atomic number of 5. The atomic number represents the number of protons in the nucleus of an atom. To find the number of neutrons in boron-11, you can use the formula:
\[
\text{Number of neutrons} = \text{Atomic mass} - \text{Number of protons}
\]
For boron-11:
- Atomic mass = 11
- Number of protons = 5
So:
\[
\text{Number of neutrons} = 11 - 5 = 6
\]
Therefore, a boron-11 atom has 6 neutrons.
If considering other isotopes, like boron-10, it would have 5 neutrons (10 - 5 = 5). But for boron-11, the number of neutrons is 6.
\[
\text{Number of neutrons} = \text{Atomic mass} - \text{Number of protons}

For boron-11:
- Atomic mass = 11
- Number of protons = 5
So:

Therefore, a boron-11 atom has 6 neutrons.
