To find the number of neutrons in an atom of phosphorus (P), you can use the following formula:
\[
\text{Number of Neutrons} = \text{Atomic Mass} - \text{Atomic Number}
\]
Given that the atomic mass of phosphorus is 31 and its atomic number is 15:
\[
\text{Number of Neutrons} = 31 - 15 = 16
\]
Therefore, an atom of phosphorus has **16 neutrons**.
\[
\text{Number of Neutrons} = \text{Atomic Mass} - \text{Atomic Number}
\]
