The atomic number of an element is the number of protons it has. For an element with an atomic number of 6, it has 6 protons. The atomic mass of an element is approximately the sum of its protons and neutrons.
To find the number of neutrons, you can use the formula:
\[
\text{Number of neutrons} = \text{Atomic mass} - \text{Atomic number}
\]
In this case:
\[
\text{Number of neutrons} = 15 - 6 = 9
\]
Therefore, the element has 9 neutrons.
